XMPP Server and Clients for small business

[Ryom]

I'd like to get some thoughts from anyone who has implemented XMPP for Windows server, with client software for a LAN. Ideally free software (even for small business use) but pay software is ok if that's what you've got experience with. In short, some of our employees are looking for a secure internal chat program (no AIM, IRC, etc), I'm familiar with IRC already but have no experience with XMPP.

Openfire and Spark? There are lots of free/open source XMPP clients and servers out there so it's really a matter of what features you need.
