Pligus is a new free web collaboration and conferencing service which allows you to create a permanent and “persistent” collaboration workspace in which to meet with your contacts.
Plingus works across operating systems, and it integrates video, audio conferencing, white boarding, screen-sharing (Windows only), map sharing and text chat. The free version accomodates up to 4 concurrent users per session, but doesn’t allow for private rooms and it is ad-supported. The paid version runs $19/month, can have up to 20 participants, has priority support, private rooms and no ads. Actually, you can even start a collaboration session without even registering.
