Personally, I think all patents--including the non-obvious
inventions--are ridiculous and only serve to stifle innovation out of
greed.

There, that's my opinion on the matter.  :-)  I hadn't brought it up
earlier because it was really irrelevant (IMHO) to the core of the
discussion we're having.

Facts, as I see them:

1) FreeTDS is an open source project.

2) Contributors to FreeTDS can opt to implement materials covered under
   Microsoft patent using the Microsoft Open Source pledge.

3) Applications may link to FreeTDS, which is LGPL'ed, as long as they
   comply with the LGPL.

My hypothesis:

4) re: #3, such applications are also protected as the infringing
   portion (FreeTDS) is covered by the pledge, and applications are
   simply consumers of FreeTDS, which is protected by the pledge.

You think, however:

Perhaps someone can get the FSF to get a real attorney to review this
matter and write something that constitutes legal advice on this matter.
