To me, merely encrypting the transport layer via SSH is far from secure, especially when the network is used by "hackers" and "freedom fighters". Today, if a network wants to be immune from tracking by design, it should officially support to be accessed from anonymous networks. The UUCP protocol is perfect for relatively high-latency, low-bandwidth anonymous network, like Tor or i2p (Particularly, i2p by itself is a great project, the only issue is the latency of the network is too high for HTTP), it would be great if some Tier 1 hosts can be accessed from Tor/i2p via a raw TCP socket (without SSH, since it's unnecessary and increases overhead in these networks). Illegal content and spam can be a problem, only peering to reputation hosts can solve the problem at large.
