If you are concerned about the free-rider problem, why not dual license under AGPL?
It's seems sufficiently "viral" that most commercial entities will elect to take a commercial license, but it allows the source to be leveraged by other open source projects. The only downside is that AGPL does not seem to promote a lot of contribution - but I gather that is not your main concern.
