Insurance
The hackerspace talk "Building-hacker-spaces-everywhere-Your-excuses-are-invalid " has a little info on insurance. One creator explained insurance was 2k a year Noisebridge. They talked about it being easier than you thought to insure something with the name 'hacker' in it. Some also had success getting insurance as a vocational school. Others claimed commercial general liability was appropriate, where they just request you inventory your tools and those are what they cover.
I would definitely like someone to make some calls and log their results here
