If you use Google Chat within a company and want to encrypt messages before it leaves your machines and goes to Google, then there is a program that can help: http://www.cypherpunks.ca/otr/
It basically is a plugin to most chat clients to encrypt and decrypt invisibly as you chat.
Only works on desktop clients though, and requires the other person to have it installed. Hence... it suits company-wide communication well as you could ensure everyone installed it.
