So you need Instant Messaging for your organization, in the office and for remote users. You are not comfortable with AOL-Time Warner (or anyone else) reading and having rights to everything you IM. You need strong crypto to ensure authenticity, integrity, and privacy. In my case, I would like offline message delivery, but I do NOT want to store messages ANYWHERE. They need to just go away when the client window is closed. What do you guys use? I'm looking at Jabber, which can do SSL, but GAIM (the best client for it, with swell windows support) doesn't support that. I'm also looking at SILC, which seems real secure and has good GAIM support, but must be run on Linux/BSD. Which is fine, I guess, but Win2K support would be great. Zephyr is supported in GAIM, but the server looks to be complicated, and again its *nix only.
