I wonder how hard it would be (and how acceptable it would be) to add 
some verbiage that patches submitted to MIMEDefang for inclusion in the 
project become the property of you and/or Roaring Penguin, solely for 
the purpose of ensuring that these issues don't become a problem.  That, 
or you'll have to start tracking individual contributors for the purpose 
of ensuring that license changes are acceptable.
