I know this. But with dynamic compilation you can get close to 100% speed. Think about it.
If I have seen a single piece of software where a patent should be supported, this is it.
I disagree. I'm 100% sure that if I spend one week full-time figuring out how to do VM with x86, I'll find a way. And this way will probably be the same as VMWare, especially because the constraints are fixed (Pentium+ limitations). It is just like finding a "mate in 4" on a chess position where there is only one or a limited number of possibilities.
And also note that the Virtual Machine concept is very old ; what is not immediatly obvious are the tricks to get 100% speed on Intel processors, no more. One shouldn't get patents for tricks on broken hardware design.

What the people in VMWare have got that I didn't ? PhDs? I'm a PhD student.
Remember, exactly because of the nature of the task, trying to virtualize tne x86, is again very much like trying to find a mate in 4 moves in a chess position ; and not like trying to write a beautiful poem or not exactly like inventing transistors.
You just have to sit, take a pen, a paper and the PentiumII specs (available at www.intel.com), and analyse how each concept and instruction can be virtualized ; how each mechanism can be used for virtualisation ; and how, for instance, the kernel behave in level 0 mode. This is a logic exercise.
Maybe I would take more than one week full-time to figure out ; because experimenting to see how real code behave could take time. But then it is almost impossible that given enough time the/some solutions can't be found. The only problem would be if they were using undocumented features of processors (but they shouldn't, VMWare works on K6 as well as Pentiums+).
Maybe people already know how to do this in theory for x86, so you're maybe asking "what the guys at Vmware have that others haven't ?" : well, they have been doing virtual machines for years, they have done research about this (SimOS), it is logical that they were the ones that started VMWare (or were hired there). Now if you show me an identical effort with enough financial support that would have failed, you would have a point.

Well the reality is more complex than that. Kevin Lawton has been trying to make an x86 emulator for longer than the Vmware start-up existed (and I actually booted Linux kernel one year ago with Bochs), so this is on the plus side for him. On the other hand he is attempting to basically kill Vmware business (by providing a free clone), while trying to keep his own business alive (x86 emulation with dynamic compilation), which is a lot less cool. Maybe you should consider that this is like "Netscape releasing source code of Mozilla to compete Microsoft", or "Microsoft releasing IE for free to compete with Netscape", depending on your point of view.

I hope VMWare gets direct x working sometime in the future and there is not too big a speed hit. However this company has done an incredible job already and should be commended for cutting down many office's barrier to entry: no MS office on Linux.

Don't steal any IDEAS!? The word steal tries to bias the thing, but even so the comment is strange.
Not that I agree with the possibility of software patents anyway, but let's just assume we are talking about ideas that are not subject to patents (prior art, insufficient originality, etc.). Taking ideas from products in the same area is one of the major inspirations for making any product better. It is not about "stealing code", but just about doing what winds up working well.
Just a trivial example. I think that the idea of creating a real-time markup spell-check flags in a word-processor is a pretty good idea. It can be implemented better or worse, of course; but it is sometimes useful to see an unobtrusive mark (like a special color underline) by words that are possible misspellings. Sad to say, the first product that I know of that did this was MS-Word (There may well be a prior example that I am not familiar with). It is hardly WRONG for WordPerfect (which I actually use, and is better than MS-Word in many ways, including its implementation of this feature) to implement this same useful feature. Corel may well even have gotten the idea from MS's implementation of it.
Further, it would not be wrong for me to add this feature to an Open Source editor that I wanted to contribute to. If the idea is a good one, more power to whomever wants to implement it. That leads to software innovation, and generally improving products.

Java uses a protected, virtual Java machine, which also is available in hardware implementation.

of the CPU and IO devices has been done in
bochs (http://www.bochs.com) for quite some
time now.
There's ongoing discussion on
news://news.redhat.com/redhat.projects.freemware
You can also search comp.emulators.ms-windows.wine
(using dejanews) for a discussion I had on how
to do this awhile ago. I'll be rehashing some of
this stuff and posting it to the newsgroup above, probably after I get back from Linux Expo.
