Yeah, I've Got Yer Four-Way Chat RIGHT HERE

I work remotely.

As such, there is a need to communicate with co-workers, some of whom also work remotely. Recently we had a meeting where someone was showing off a secret-squirrel new website and how it works and how we might integrate it into our project.

Hence, the four-way video chat:

(Identities have been hidden to protect the innocent.)

The screen on the left is actually local to the screen in the middle; the rest of us wanted to see what was on the middle guy's screen.

Not perfect, but it worked.  And it was lagless, I might add.

iChat is my friend.
