Done.. You should have the necessary source code snippets, etc. I may
talk my boss into letting me release the control functions rewritten in
PHP so others may use them. They will require PHP compiled with
functioning
regex, mcrypt, mhash, etc... but should come in handy for anyone wanting
to work with SRS in PHP3/4.

I may be wrong, but using either OpenSSL or OpenSSH with a non-RSA
encryption scheme should be legal. Niether piece of software has
any sort of restrictions, but I know RSA has patents on some of the
encryption schemes here in the U.S.

I believe it was in an email from Ross, but it wasn't anything
definitive,
I was gambling a bit with my time on that one (although the work I did
there
will be useful on other projects). If you are interested in
implementing
an SSL or SSH gateway port gateway, and need any ideas... let me know.
The
changing of encryption didn't really bother me, although the major
change in
the protocol caught me a bit off guard. (going from a clear text
protocol to
using a packed 16bit integer to list size of message being sent.)

Great. Fortunately I'll be on the slopes that week, so it'll probably
be waiting
for me when I return. I appreciate your help!
