I'm not disagreeing with @pg but instead of trying to build a business/startup I'm developing a FOSS project called SmallCommunities (http://github.com/billsaysthis/SmallCommunities http://github.com/billsaysthis/SmallCommunities). It's written in Rails and is intended, at least at first, to handle groups which have regular events and (paid) members. Always happy to have more collaborators.
