Hi,

I have found this website: http://sebsauvage.net/punching/.

Maybe it would be very useful to build this into TorPark.

The problem

Say you want to fetch your mail from your ISP mail server. You usually 
simply connect to port 110 on the POP server of your ISP.

Trouble: there is a Big Bad firewall which blocks everything.

Well... it does not exactly block everything: it lets HTTP out through a 
proxy.
Let's encapsulate our POP3 connection into HTTP.

For more see: http://sebsauvage.net/punching/

P. S. It is not just corporate firewalls. It can also be governement 
firewall...

bye, Matej
