SecureXMLRPCServer module using pyOpenSSL 0.5

Extremely kludgey code written 0907.2002

by Michal Wallace ( http://www.sabren.net/ )

This acts as a drop-in replacement for

|
SimpleXMLRPCServer from the standard python

library.

This code is in the public domain and is
|
|
provided AS-IS WITH NO WARRANTY WHATSOEVER.

SSL Connection tends to die on sendall,
