Right about now, Convoq is on the stage at Demo. They just announced ASAP Express, which provides free 1-to-1 conferencing, video and IM. Upgrade to ASAP Pro and you get a low price alternative to WebEx. One of the things they are showing is how Socialtext and Convoq work together.
With Socialtext Workspace 1.5 we added Convoq presence links. All you have to do is type "convoq:asapname" and you get this:
People use Socialtext and Convoq in tandem. When working on a document within Socialtext, you can escalate to real-time with a shared view of what you are editing. While in Convoq, when the meeting ends, you can de-escalate to asynchronous and more persistent collaboration.
With similar support for AIM, Yahoo! Messenger and Skype, you can also do simple things like a presence dashboard for a team or simply make your contact information richer.
