What would people think of a website that collates instances of companies taking legal action against employees regarding side projects and then ranks them with respect to 'side-project' friendliness? Would a bad rating for a company impact your decision to take a job there?

Also, it would be cool if there was some widely available standard 'developer friendly' contract (or even addendum to a contract) that software engineers could table when negotiating a new job. It should be fair to the employer too of course, but it would give less experienced developers or those in a weaker negotiating position for whatever reason something well thought out to use.
