Zephyr is a lovely "IM" type client that I've used since the very
early 90's.  Speaks Kerberos (encrypts the comms), but I haven't
found a decent Windows Zephyr Client (or a Zephyr -> windows
messaging thingy translator).

I also use IRC on a home machine for chats with friends and
relatives.  Not open to all, but handy to have.
