I've now built a framework in test_ssl to test all client protocols
(SSL2, SSL3, SSL23, TLS1) against all server protocols, and here's
what I've come up with.  Servers are along the X axis, and clients are
on the Y axis.  "Yes" means that that client protocol can talk to that
server protocol.

        SSL2    SSL3    SS23    TLS1
SSL2    yes     no      no      no
SSL3    yes     yes     yes     no
SSL23   no      no      yes     no
TLS1    no      no      yes     yes

I'm a bit surprised by the facts that (1) an SSL2 client can't connect
to an SSL23 server, and (2) an SSL23 client can *only* connect to an
SSL23 server.  Can anyone verify that these combos (the results of
testing with the Python framework) are indeed to be expected?

Bill
