Now here's an important detail that needs to get done right. Is the forwarding for fixed length packets, variable length packets, or streams? Is this decision global or local? What are the latency and aggregatation effects? How important are these for different classes of data? (telnet v. voice, e.g.)

I'm not sure I understand the first question. My idea was originally based on link encrypted streams. How can forwarding variable length packets help untracibility? Wouldn't an attacker just have to match up the sizes of incoming and outgoing packets? Forwarding fixed length packets, on the other hands, just makes the system a remailer-net (so you'll have to do mixing, etc.). What am I misunderstanding here?

I'd suggest just getting something running first, to get some prototyping experience.

I just finished hacking ESM to do link encryption. (see my other post) Now if someone is willing to run a MUD type program and hook LESM up with it, then we'd have the first prototype of a pipe-net.
