Apologies for the lack of updates recently, it's all my (+Peter Chapman) fault. I've been told not to neglect our beautiful G+ers anymore so I'll start adding some of our highlights again and you guys help us out by sharing them, okay?!
Just been reading that the g+ hangout API is out for people to integrated into their Web apps. Has some interesting features in it now with screen share, Google doc access and youtube sharing. Sounds like it might be more useful for the TSA team rather than the users though.
