How to conference call:

Open up a copy of google talk on all computers with which you wish to conference.  After one copy is opened make a new shortcut for google talk but at the end of it add /nomutex.  If you installed it to the default folder then your shortcut should read "C:\Program Files\Google\Google Talk\googletalk.exe" /nomutex.  Open 2 instances of the software on every user's computer.  After this start a chain: User 1 should connect on one instance to user 2.  User 2 will connect on his second instance to user 3.  User 3 will connect using his second instance back to user 1.  With this chain everyone is connected to everyone.

Possible problems:  Google will try to connect you with others on the same instance.  To fix this just open a new instance. It seems that google will try to take calls on the newest IM client.

Note: You can also make a conference call with more people, just have need to have one less instance than the amount of people that exist.
