IEEE488? I was considering building an interface to that once (y'know,
just for fun :-) and I have a friend with some old PET hardware (or was
it CBM? I dunno)... we found that we could link both the computers
to the disk drive with the funny bus thing, as long as we were careful
not to cause a collision, thus implementing a... file server?!?!?

Sadly a bit complex, though :-(

Indeed; and the MLM protocol wouldn't be used for EVERYTHING. Just
tasks on the kind of level that humans are likely to be interested in.
Anything needing performance can go use byte streams and net blits
for all I care... I was planning on making a /dynamic/ protocol stack for
ARGON's IPC, you know!

Commit yourself, Fare... what kind of network protocol DO you want? :--)
