Yeah, I had thought about that. There seem to be allowances in most places for small scale things. I can't run a restaraunt out of my house, but I can throw dinner parties every so often (even in exchange for money). People can't walk in off the street and hand me money for food, but I can have small events with predefined people.
It is a bit of a gray area, but it's my opinion that the benefits outweigh the risks. I could be alone though.
