I don't think BitTorrent's popularity proves this at all, I don't have
the statistics but I suspect that the vast majority of BitTorrent
users do not set up port-forwarding.

We used TCP prior to Freenet 0.7, and learned the hard way that TCP
simply isn't the right tool for the job, it does a bunch of things we
don't need (such as guaranteed in-order delivery), and can't do some
of the things we do need (such as NAT traversal).

I do agree that we need to work on disguising Freenet traffic, but
there are no shortage of UDP-based protocols that we can use for cover
(eg. Skype).
