Dimdim, a free, client-less web conferencing solution, just exited beta with version 4.5 today.

According to Dimdim:

"Especially in this current economic climate, there is no justification for proprietary, closed, or support-heavy technology that costs you in multiple ways," said Prakash Khot, co-founder and CTO of Dimdim. "With our new Dimdim 4.5, there now exists a solution that enables everybody to communicate online in the most efficient, synchronized and cost-effective way ever possible. Dimdim simply removes the need for needless travel, complicated web conferencing and unnecessary downloads."

Unlike LiveMeeting, WebEx, GoToMeeting and other web conferencing solutions, participants don’t need to download an entire client to attend the meeting (although they do need Adobe Flash to be installed).

As with other web conferencing solutions, Dimdim provides slide sharing, Mac & PC screen sharing, audio and video conferencing, along with a long list of other useful features.

Dimdim is free for conferences with up to 20 people.  Their Pro accounts start at $99/year, and Enterprise accounts with up to 1,000 attendees are $1998/year.
