I was worried for a bit because I thought there's new competition for our Munchery (http://gomunchery.com), which is much more like Airbnb for food. :)
Hmm. I think this will be very much like AirBnB for food, but it's in a gestation stage w/kitchen show-off shots to build a community first.
There's also Mealtik, which is AirBnB for food.
Ultimately, I hope all three (or more) you folks go big, as the biggest problem will be skeptical customers and perhaps buzzkill regulators (like AirBnB in NYC is up against).
Having a bunch of momentum + market examples and flavors is the best way to get past all this.
