nelsonrn writes "Two university groups are working on designs for tiny Linux boxen reminiscent of the Compaq Itsy: UNSW's Pocket Linux Embedded Box (PLEB), an Intel/ARM SA-1100 based box, and Ryerson's uClinux simm, a 1" tall Motorola/68K Dragonball-based Linux box on a simm. Both have serial ports and LCD interfaces, but the PLEB has IR and the uClinux simm has Ethernet. Both ports are booting on their respective development platforms. Coincidentally, both projects are currently laying out their boards in preparation for a run of prototypes."
