  This is a subset of the idea of an "async gateway processor",
which is a small, general-purpose computer gutted to run several
gateway programs.

  A plausable set might be:
        IP to ordinary ttys (ie, normal TACyness)
        IP to SLIP
        TCP/IP telnet/TACyness kermit (recent large-block kind)
        TCP/IP telnet/TACyness to MNP (a mostly-transparent modem protocol)
        TCP/IP telnet/TACyness to X.pc (if you feel masocistic)
  A good cantidate for such a machine might be one of the
"unix-like" small realtime systems running on mas-market hardware.
