I've used this in the past with other traders: http://www.tradingrooms.com/
Have you used it before? It works pretty well overall and it's free. Let us know if you create a room there.
EDIT: Just logged in to tradingrooms and it's fairly straightforward to create a room, but I'm not sure how to share charts. You might have to play around with those features and I'm assuming trading hours probably aren't best for that. Well hopefully we'll be able to figure something out.
