Would it be consider kosher for the following _additional_ requirements to be placed
on an application (X) which was covered by the GPL:
 
1) Users of application X or derivatives must register with the company that 
   originally created application X.

2) If  a company using application X ships a derivative of application X outside their own
   company, they must also ship a copy to the company which originally wrote application
   X.


Now, I guess there are a couple ways that this could be viewed, the cost of registration and
shipping derivative  programs could be viewed as a cost. Still, these are mechanisms which
might need to be put in place to insure that there was some kind of central clearinghouse
that users could be guarenteed at least has had a chance to see all varients of an
application.  My sense is that the authors of the GPL sort of assumed that everyone is on
internet and derivative programs would just sort of pop up there. I'm not sure if this is
entirely a good assumption in the case of applications programs which are used in
environments where people don't have internet access.
