Tom Keating has a post this morning about a preview of the new Microsoft Office Live Meeting 2007.
According to Tom:
The new Live Meeting client integrates multiple communication channels for a unified experience. These channels include VoIP and PSTN audio, live and recorded video, screen and document sharing, chat, and audience feedback tools.
I urge you to check it out. As usual, Tom offers lots of insight and even a bunch of screenshots to illustrate his experience.
