On-line live analysis board? Here is the situation. I have a friend with whom I very much like to discuss chess (our games, other games etc.). We are not living in the same country, so we discuss chess on-line. During our on-line discussions, we often, of course, need a chessboard. Usually, we use our wooden chessboards (which we see through our computer cameras), but this is inconvenient, as it causes synchronization difficulties. 

My question is: Is there a site or a chess program with a chessboard which both my distant friend and me could see and alter, in such a way that every change in position is simultaneously shown to him and to me. In other words, something like a "live analysis board". If we were at the same place, we would have a chessboard on which we would analyze a game. He could alter the position, and I would see it, and vice versa. Now, I need the same thing, just on-line. Does anybody use something similar and/or has a suggestion? 

I hope my description above is enough to understand what I mean. Obviously, my English is far from perfect, but I hope it will do.

Finally, I would like to stress that I am NOT asking for a suggestion for a site for PLAYING chess, but for ANALYZING games and discussing different positions. 

Any suggestion would be appreciated. Thanks!
Chess.com has an analysis board meant for doing analysis with other people. But its available only for premium members. Also I am unsure if it has voice support in built when doing the analysis.

For the free alternative, its worth to look at FICS- It has a very cool feature for analysis called "examine", that combined with "mexamine" will give you exactly what you are looking for. Along with this, you could just setup a skype or gtalk (replace your fav free voip program here) for chatting with voice when you are examining the game. You could use Babaschess the free and best FICS client available.
