With the upcoming OCS 2007 R2 CWA, you can take it a step further on the Mac or Linux browsers where you can join a PC desktop sharing session and view and collaborate with their desktops. There may be plans to allow for Mac to host at some point in the future (always subject to change of course).
What about On-Prem OCS Live Meeting support?
Currently, there is no Mac support at this point but the alternative solution to this is to use the Communicator Web Access coming in R2 to join a shared desktop session.

Is there any policy template? For example if I wantd to not display the video call options?
videocalls and audiocalls actually works on this windowslive messenger 7 mac ?
or do i need Microsoft Office Communicator 2007 R2. to let the videocalls works ?
You can do video and voice over IP calls similar to commercial IM voice and video calls. What doesn't work without something like Fusion is PSTN voice over IP calls outbound or inbound such as to a PSTN phone from this client.
I am not aware of a Mac policy template to prevent video calls.
