The RSA patent expires September 21st, expect to see many encryption
programs relying on RSAREF to have new versions out around September 22nd.

Export restrictions for encryption software that doesn't require a license
payment seem to be gone, at the moment away --
http://www.bxa.doc.gov/Encryption/qanda.htm  
Note the crystal clear language used in this document.

Case in point, redhat distributes OpenSSH and OpenSSL RPMs on ftp.redhat.com
ftp://ftp.redhat.com/pub/contrib/libc6/SRPMS/openssh-2.1.1p1-1.src.rpm
ftp://ftp.redhat.com/pub/contrib/libc6/i386/openssl-0.9.5a-1.i386.rpm

The web pages for those packages don't indicate if they use full RSA or
RSAREF, and I suppose it's possible that redhat got a license for the RSA
patent at some point in the past that might make that question moot.  As it
stands, since Corinna's version uses full RSA, it can't be downloaded by
anyone in the USA without violating the RSA patent for the next seven
weeks.  After the patent expires, I'm not sure there would be anything
preventing it from being hosted on a site in the US, until of course the
next random encryption policy change.
