OK, this works, but what if I have a client and a server that knows nothing 
about SSL, e.g.

I've got a windows vnc server configure like this:

[VNC]
accept   = 5901
connect  = 5900

And then on the linux client:

[VNC]
accept  = 5901
connect = 192.168.100.57:5901

The vncviewer just hangs:

Again the same result in the log file:
