Dual license for static linking

[charliewolf]

Would you consider licensing this as a dual license GPL/MIT (so users have choice of which to use)? I'd like to release an app that has sipster statically linked to pjsip but I can't statically link the two together currently legally (at least, without buying a pjsip license, but that would escape the point since I'm trying to release an open source app) because PJSIP uses GPL and sipster uses the MIT license. Let me know what you think. Thanks.
