SSL provides a 1:1 cryptographic protection of a TCP connection. For
additional services (e.g. multiple data streams) you either need a
different protocol (e.g. http://www.ietf.org/rfc/rfc4251.txt), or an
additional proprietary protocol encapsulated within the standard SSL
(so called "SSL VPNs" take this approach). Please bear in mind such
"SSL VPN" is no longer just SSL encryption, as it needs this
proprietary protocol implemented on both ends. Stunnel does not break
SSL this way.
