Github could do it. Doesn't look they're rebranding into Microsoft Code Office Space (TM) any time soon. And one would assume they'd put the licenses on Github as well, so you could suggest changes and sell your project on whichever version of the license you want.
What Github would bring to the table are easy marketplace dynamics, trust, and a team of lawyers capable of writing good licenses. Also, the same code analysis tools that check for security problems in your dependencies could also license checking. There's a very compelling use case for businesses if all their code hosted on Github can 1) automatically check for license violations and 2) just pay for all licenses on a single screen with a single click.
