A dual license with the GPL or QPL and a commercial license would meet your 
needs.

No it would not. The OSI definition says "The license must not place 
restrictions on other software that is _distributed along with_ the licensed 
software." [emphasis mine]. Therefore so long as the license only 
"contaminates" itself and derivative works, there would be no problem.
