For those of you forced to communicate at a distance with your friends or colleagues, Yugma offers a free alternative to some of the spendier web conference options out there. Yugma lets you share your desktop with up to 10 people at a time (for free - you can pay to add more), and connect in with teleconferencing. I’ve read some complaints about Yugma not really being free if you still have to pay the long distance fees for the audio conferencing portion, but if you and your pals are all on Skype, you should be able to work around that fee as well. In addition to the teleconference part, there is also an IM feature, and depending on what type of information you’re sharing and your typing skills could be just as useful as the teleconferencing option (my in-laws have done this for inter-continental family check-ins; it worked swell). Another potentially nifty feature is the ability to change presenters so multiple people could be involved in sharing a discussion instead of just one centralized presenter. While this may not be the tool for a full-on webinar, this could be just the thing for sharing ideas or applications with a couple of colleagues who don’t happen to be sitting in the cube next to you.
