   What is the best way to approach the problem of
   getting "A" unix(ultrix) mailer to broadcast a
   notification of the arrival new internet mail to the
   screens of specific PCs [and MACs] on ether with NCSA
   telnet installed.  Note, I said installed, not necessarily
   running...

What you need here is a DOS/MAC TCP/IP which is resident (like part
of the OS), not transient (like NCSA, KA9Q or PCIP).  We have done
this with our 2.0 release (but no joy on the MAC).  Stanford has
said in the past that they were working on a TSR TCP/IP for DOS,
but I don't know if they have finished it (you're non-commercial,
so you can use theirs).

When we first released PC/TCP v2.0, I did a little TSR using our asynch
notification facilities.  It sits there and waits for datagrams, when it
gets them it writes the text contents to line 25 of the display (direct write
to screen memory).  This will be in the next release of our Dev Kit as an
example program.

Doing something like this with a resident MAC TCP/IP should be pretty
easy, but NCSA is monolithic (nobody is listening if the application
isn't running, and only one application can run at a time).
