	Finally I'm seeing the point you've been trying to make. Ok so the
licening needs modification to be made more relistic. 

	The thing that I've not understood is why this is a problem? The
restrictions you mention seems to be just as applicable in the GPL, it you
can't restrict what someone does with the end program, only how they
modify the specifically GPL'd source code. What forces to use the GPL is
that its easier then rewritting the code.
	But thats off the issue at hand and I think we are all pretty
clear on that now. 

	So back to the licencing, Graham, are the openip guys on this list
so they know RMS's comments on the licence?
