Presumably this won't affect the non-US keyservers.  I don't see the people
running said servers bowing into pressure about a patent that doesn't
affect them....

The thing is, though, that PGP 2.5 *doesn't* infringe on the patent,
because of the use of RSAREF.  Any version that uses RSAREF should be legal
from that patent sense.  Presuming that there aren't copyright issues
involved with the 2.5 release, I don't see any reason that code couldn't be
maintained and fixed.  I'll have to check the copyright status on 2.5 when
I log on.

There are many people, including myself, that won't get involved with an
infringing version of PGP.  PGP won't get "wide" acceptance until the
isssues are resolved.  At the same time, PGP also won't get "wide"
acceptance unless it is interoperable with the outside world.  This would
involve code using RSAREF coming legally into the US and being used, or
code using RSAREF being illegally shipped outside of the US.  Apparently,
the latter has already happened.  But either way, for PGP to be
noninfringing in the US, it needs to use RSAREF.

I'm guessing that the new version of RSAREF they announced would be coming
out will probably alter the terms to make this difficult/impossible.
However, I don't believe there is any requirement we use the latest version
of RSAREF...  Just to use the license that comes with that version of the
