     I mentioned this to a friend of mine who is knowledgable about
things like this.  He said that if Connectix uses the PMMU (which they
do) that they would be unable to patent their idea.  You might think
of it as creating the toolbox.  If you can create the toolbox routines
with no knowledge of them except for a set of specs, then they should be
legal.  Also, it would seem stupid that the idea of virtual memory
would be patentable.
