It is not widely known that Skype has provided video-conferencing from the desk-top since January 2006 (V2.0.0.69). Desk-top video-conferencing can eliminate the need for special video-conferencing equipment and rooms. For existing Skype users, the only additional technical requirement is a web-cam. The call costs are the same as for Skype voice conferences, eg. free to other Skype users.
