As far as I am aware, all of the techniques employed by these  
projects are already listed in the tickets under the "firewall" tag.   
(As an aside, Greg Hazel, who has offered to contribute one  
particularly sophisticated technique (#169), is one of the people who  
made BitTorrent.)  The need at this point isn't to discover new  
techniques (unless of course I am wrong and there is something that  
we haven't thought of yet) but to code up the docs, tests,  
integration, packaging and so on that would be required to close one  
of those tickets.
