Replacement for Netmeeting
Solution 1:
Yugma is a free alternative that I've used before.
With priced options there is
- WebEx
- GoToMeeting
- Yugma Pro
Solution 2:
Office Communications Server might not be that expensive. If your company has licensed the Enterprise version of Office, it already comes with a Client Access License for Communicator.
That makes the price of OCS only $700 (for the server), even if you have thousands of clients.
Food for thought.
Solution 3:
I use Microsoft SharedView It works great in VISTA and it's very easy to use.
Solution 4:
I'd recommend Citrix's GoToMeeting. I have used it to do both presentations and remote support. Its very simple to use and has worked very well for me in the past, even over poor internet connections.
Solution 5:
There's always VNC. The free version has some OS limitations, but works well. May not work for you b/c you have to pay for the Vista and Mac versions.
