Except that SOCS modems are typically connected to SOCS machines. Attempting
to run PPP over an 'rlogin ftoomsh' session seems revolting at best, but may
be impossible - I'd be suprised if SunOS/Solaris would accept a pty as a
network interface.

Apply to ITD I guess - but I doubt that they'll give us half a percent
of UTS's total IP address allocation. Maybe if we ask SOCS nicely, we can
steal some more of theirs :-)

Ahh, not really. It certainly should be from Ftoomsh though.
