Thanks for your license submission.  This seems to be a  
straightforward permissive license with strong patent protection  
terms; in particular, section 3(e) with regard to disclaiming  
warranty obligations seems to be well written to acknowledge that  
different legal frameworks may override such disclaimers.

The MSPL seems to be fully OSD-compliant.  Although, as you've noted,  
it is not miscible with the GPL or similar licenses which seek to  
govern how a combination is licensed.
