I wonder how feasible it would be to have rdesktop or a vnc client
write directly to a wsfb() type framebuffer, or even via SDL to the
same. Might make an '040 just about usable for a remote display.
Certainly if I was able to use a 4MB 15Mhz 68020 based sun/50 as an X
terminal we must be able to manage *something* :)

Don't forget an xneko plus a couple "oneko -toro" processes at
different speeds :)

Random thought - how much extra load would a twitter bot take? Each
machine could have its own twitter account and respond to certain
commands - uptime, df, uname, first part of dmesg. For bonus (and very
very very slow) option could even tweet a bitmap for dmesg :-p

Deadlines are quite amazing productivity devices :)
