talk doesn't work too well a) when talking from a non-sun to a sun, b) when
network bandwidth is on the order of 30 bytes a second, and c) when you
don't have a terminal capable of running a full-screen program.  While write
works for all three cases (for (b) I use 'mode l' from telnet, it helps a
lot), you need to have an account on the target machine.
