Open Source Software Alliance License

There's an interesting discusion in the thread "For Approval: Open Source
Software Alliance License".

The problem seems to be that it's basically the BSD license + this gem:

    4. Redistributions of source code may not be used in conjunction
       with any software license that requires disclosure of source
       code (ex: the GNU Public License, hereafter known as the GPL).
    5. Redistributions of source code in any non-textual form (i.e.
       binary or object form, etc.) may not be linked to software that is
       released with a license that requires disclosure of source code
       (ex: the GPL).

And while I'm on the subject of licenses, I'm quite fond of the Academic Free
License 2.0, which was approved by the Open Source Initiative Sept 3,
particulary clause 10:

   10) Termination for Patent Action. This License shall terminate
   automatically and You may no longer exercise any of the rights granted to
   You by this License as of the date You commence an action, including a
   cross-claim or counterclaim, for patent infringement (i) against Licensor
   with respect to a patent applicable to software or (ii) against any entity
   with respect to a patent applicable to the Original Work (but excluding
   combinations of the Original Work with other software or hardware).

As Larry Rosen, the license author, puts it:

   The theory behind this clause [10] is that you need to consider carefully
   before you sue an open source licensor for patent infringement.  Such
   lawsuits will no longer be risk-free.  You have the right to sue, of
   course, but you lose your license to that software if you do.
