OS/X can pretty much talk any format, including its native Appletalk. I’ve got a mixed network here (PC, Mac OS 9, Mac OS X, Irix, and Linux), and everything is happy talking everything. However, before your IT guys go nuts trying to safeguard the Macs with whatever firewall software they have, note that we’ve been running unprotected Macs since 1985, and no infections yet.
