It's 379 on DirecTV and 231 on DISH. Looks like us cable customers are mostly out of luck. A few carry it, see:

Not sure how they feel about online distribution, but it would be great if they could make the show available on their site or YouTube or something afterwards. It'd be good for the sponsors, good for promoting the channel, and would help convince those of us with cable providers that don't offer the channel to bug our cable provider. \:\)
