What it is: An open-source Web conferencing tool -- like WebEx but free

What's cool: You don't need to install anything on your computer or network to get a Web conference with audio, chat, and video. You also can track what you've presented to customers.

Drawbacks: It doesn't have a recording and archiving feature for past conferences, though that's among the features the company plans to add.

Price: Free. Support costs $8 a month, or $99 a year.
