From my understanding, there is a fundamental flaw in p2p technologies like
Freenet for those that want to deploy in highly-censored countries. That is,
it's too obvious. The censor doesn't have to know what's being transmitted,
only that /something/ is that's outside of their control. All they have to do
is disallow the ports on which the technology runs. Torrenters can at least get
around this by changing the port they're using; Freenet has no such option.
Not only does Freenet have such an option, but the default ports used are
random, thus are different for each computer it's installed on.
From my understanding of internet communication protocols, the use of udp is
too obvious; it stands out like a sore thumb. Why not tunnel the connection
over tcp? Wouldn't that prevent potential censors from differentiating it from
the rest of transmitted data? As well, wouldn't it solve the closed ports issue?
It's a planned feature, but for now the protocol has no identifiable signature.
For all intensive purposes it looks like a very long Skype conference call.
