Diskless Workstations

I have been lately coming across diskless workstations (an integrated computer without disk) at very cheap prices.
Has anyone used this type of a platform for a robotic implementation?
It would seem to be a natural for a distributed network within a robot and they seem to have a nice array of interface options.
Thanks for any advice you can offer.

diskless workstations are such a good way to go, if you don't go nuts. i'd suggest a 32bit x86 compatible embedded board on each robot, something with 8mb ram on board, simple ethernet phy with a wireless link and bootp or dhcp support on the network hardware. then on the software side, a server with clusternfs (http://clusternfs.sourceforge.net /) to prevent wasted space, but still have customised kernels and stuff. i wouldn't suggest using a full diskless computer for just a robot, but there are people who use lots more for less gain, so a diskless would be pretty good.
