[plug] tunneling windows remote desktop via my webserver on port 80

[Jason]

Ok, so my work blocks all ports except 80 and 443.

I run sshd on 443 so I can ssh home and a webserver on port 80.

I also virtual host two domains from my machine, so I can't just change 
my router to forward port 80 to my windows machine for remote 
desktopping.

What I want to do is:

Request from work goes on port 80 to my home router, which forwards 
request to webserver, which picks up that I'm requesting to remote desktop 
(possibly via the domain name, similar to virtual hosting) to my windows 
machine, which then tunnels the request and successful remote desktop 
response back through my webserver, to the router to my work machine.

Is this possible?

Hope it all makes sense :)

Jason.
