What do I gain by not using gpl? Commercial use and forking under a license of your choice. The only thing that concerns me using bsd is how to accept contributions that im not merging in safely.
Others have said here, and I agree, that if you modify an extension which uses the BSD license, then you are releasing your modifications using the license that the extension is released under.
If you want to make it really clear to people working on the code use a license header. You can see how this is done on a large projects (albeit ones that use only a single license) by looking at Emacs[1] or FreeBSD[2].
Point being: I think you're trying to solve a non-problem. If you're really worried about how to accept contributions and think your situation is truly unique, consult a lawyer. Otherwise, follow the example of others who have gone before you.
Mark.
