[plug] Slightly OT? cascading proxies

[BillK]

Does httptunnel do encrytion? - just started playing with zebbedee to
compress vnc links and it seems to have a similar ability (with
comression and encrytion), though any available ports can be used. 
Makes a bit of a mockery of firewall security where they dont look
inside of the packets!
