To set the stage for some of the tools that I will be discussing here I figured I'd outline some of the collaborative tools that I currently use, and mention ones that I've recently (within the last few months) have evaluated. I'll likely be revisiting some of these tools in the near future. The software is shown in categories (as I evaluated them) below.
I've left off some of the obvious players in the IM and VOIP space (e.g. Skype), though some new players in that space may be later included. The software that I use regularly includes MovableType (here), MediaWiki, KwikiWiki, Joomla, Drupal, Moodle, Roundcube, Google Calendar and Google Docs. I'm still on a quest for the perfect document/group collaboration software. And that quest continues...

I blog for the Collaboration Loop and work for Collanos and would like to get in touch with you about your interest in Collaboration. When you get a chance send me an email and we can chat.
