Hi Shane, Great timing :) Tony and I have been bantering for a few weeks about getting the BarCampNYC6 ball rolling, and it's wonderful that you're up for heading things up!
Thankfully, you're in a great position to get this BarCamp off the ground - Max, Tony and I are here to help and support you through the process with advice, connections, and grunt work, and there are a few venues ready and willing to host if they're up your alley!
I've been chatting with the GA folks, and they're very interested in supporting BarCamp up to and including hosting it. I believe Tony would also be up for hosting at New Work City if you decide to go with a more intimate Camp. I haven't spoken to Pete at Microsoft about it, but they've always been friendly and inviting, and the folks at ITP might be interested again as well if you approach them.
Essentially, one of the first things to do is decide what type of BarCamp you'd like you put together, mostly influenced by the number of attendees you plan on inviting and how focused you'd like it to be.
The New York tech and startup scene is extremely active at the moment, so there's a chance to bring together a huge crew of smart people to share their knowledge. You could also keep the camp smaller, and spread the word more organically, to encourage a more focused event.
Either way, so awesome to hear that you're interested in picking this up and running with it! Let me know if there's any way I can help.
