No problem at all. You reconfigure the firewall to allow your 
protocol through. Simple, isn't it?

If you can't, or your administrator won't, then your protocol should 
not be going through the firewall.

"Bypassing firewalls" is traditionally called "cracking". It's only 
comparitively recently that people have felt the bizarre need to wrap 
every protocol in HTTP in the belief that if they don't have to 
reconfigure a firewall, this makes things more secure.
