The patent never expired.  It was due to expire in September 2000; in  
August 2000 the patentholders released it into the public domain.   
Some people (myself included) think they did this in order to prevent  
the media coverage of patent-expiration celebrations.  I was really  
looking forward to the party Network Associates (then the owner of  
PGP) was throwing, and then got cancelled.

No; only people using OpenPGP applications that don't support RSA will  
have problems.  This is potentially quite a lot of people.  The last  
time I tallied it up there were at least ten different OpenPGP  
implementations, and some of them only support the bare minimum
