Why SSH rather than SSL/TLS ? For an SSH based system, I'd rather expect
that a regular TCP/Unix DBus channel would just be tunnelled over SSH, in 
much the same way as X is tunnelled.  For a built-in encrypted transport
simply leveraging the SSL/TLS protocol is the more common approach. One
can use any of OpenSSL, Mozilla NSS or GNU TLS libraries for this, though
the latter two are preferred for ABI stability & licensing terms. Its
actually surprisingly easy to hook these into existing apps with very
little changes to existing code required.

Dan.
