We run an internal Jabber server which all employees log into. This
eliminates the reliance on an outside server (AOL/Yahoo/etc) as well as
the security concerns of same outside servers.
Of course it's still cleartext over TCP, so it's not 100% secure but it's
localized traffic.
We find it invaluable especially since our department has become
geographically diverse. To be able to pop "Can you look at TT#XYZ?" vs an
email or phone call is quite nice.
