I suspect this is probably sufficient for Debian's purposes, although I
of course can't speak on their behalf.  Whether it is suitable for Red
Hat or other organizations with strict patent policies, I don't know.

My personal view is that using patented algorithms[0] will prevent at
least some adoption of the OpenPGP standard, even if that's overly
cautious and defensive, and that there are sufficient secure
alternatives such that we don't have to use patented algorithms.  The
less we can make implementers get lawyers involved, the better.

Clearly this is not suitable for Debian's purposes, as they prohibit
restrictions on fields of endeavor.

[0] By "patented algorithms," I mean those that don't grant a flat
royalty-free license.  SHA-2 is patented, but available under such a
royalty-free license.
