I like this. I think people frequently underestimate the disadvantages of having team members work from home. Sure, basic tasks can be done remotely ("set up this database xy, perform maintenance work here etc") but all other tasks require collaboration. Having everyone in IRC will help, but it is not the same. People will not talk to each other the same. This is where video, instead of Skype calls or similar, might really help.

Edit: By all means put up screenshots so one can see what this app looks like.
