I know that there is(or was) a place like you described for book authors on Google hangout. They would just meet in a room and not really have a conversation but only be present. The goal was to get a motivational boost by seeing other people working and doing the stuff you should be doing too, which in that case would be writing. I imagine it could work for some people. So I say try to find something on Google hangout. And when you have found something tell me about it :)
