All we have is KA9Q. I have a /inet server mostly married with it, which
permits programs to open, say, /inet/tcp/25, and take the SMTP port for the
box.

I don't know if the version of KA9Q I ported is up to the task. In any
case, it should provide some shortcuts for the port of some other networking
code.

I have a dream that my annual bonus (coming out in a couple months) will be
big enough that I can "sneak in" the purchase of a dual processor Pentium
system. Until then, the only sanity checks which have been applied to the
SMP support is kernel preemption, and my experience doing SMP at Sequent.

This was the primary motivation behind getting /inet up and running. I
wanted to map VSTa messages over a box-to-box protocol, and thus be able to
access an arbitrary VSTa server from any other box. This would provide the
starting point for clustering.
