No.  This violates the basic rules on the legality of reverse
engineering and clean room development.

Per this logic StarOffice, AbiWord, etc are subject to Microsoft's
licensing for Word due to the fact that they reverse engineered and
implemented support for Word format files.  Intellectual property
doesn't work that way (tho it gets close to being as stupid as
that).

cf The Apache licenses.

More simply: 

  You get to maintain a closed source branch.  

  Others also get to maintain their own closed source branches.

  Others don't have to reveal their branches (in normal operation)
  as they are not distributing their product it, merely running it.

  You get to see (and take advantage of) any distributed
  changes/patches.

  All the other closed branches get to see (and take advantage of)
  any distributed changes/patches.

Heh.  I assume you've noticed the new  licenses on beta MS dev
products:

Methinks I detect King Canute.
