Hackerspace run as a business, paid for by equity?
prospero: In this scenario, the longer a company goes without succeeding, the more money they cost you.  If the equity cost were recurring it might work, but if the company doesn't steadily grow you'll just consume it all until there's nothing left.At the end of it all, you'd be left with 100% of a worthless company, and out the cost of all those meals and games.  I dunno if your potential successes would offset all that.
