One problem is that advances in such networks generally require implementing entirely new networks to check out new algorithms and new features, such improvements are strongly deterred. After all, that's one reason that TOR doesn't get as many improvements as we might like. (Another reason is that it is financed, at least in part, by people who are hostile to a "too-good" anonymization system.)

Internet services are provided with as much as 1 terabyte/month capacity, and possibly unlimited as well. (CenturyLink 1 Gbps, for example) We could implement a new onion-routing system, akin to TOR but with some improvements, most prominently adding chaff. So far, so good. But there may be other ideas, other improvements that people might want to try out.

The big impediment to this is that people naturally want to avoid the potential legal harassment they might get if their IP node sent out gigabytes of 'in the clear' forbidden data. My ideas for a solution? Output data could be encrypted, enough to make it unreadable except by the end recipient. The operator of an output node that emits only seemingly-random data would be hard to hold legally responsible for that forbidden content, since nobody expects him to know how to convert it into plaintext. And/or, the data can be output into two streams, which would be XOR'd with each other only by the intended recipient to find the data.

Why shouldn't it be possible to serve two algorithms? Or dozens? How about Bittorrent as well? Imagine 1000 nodes, each equipped with a 10-terabyte hard drive?

I am preparing a draft of a draft for a spec of what I think would be the ideal complimentary anonymization overlay that fits on the already running distributed system I am working on, which is USPS and is very good.
It would be great if many ideas arise in this list so we can start focusing a conversation. My personal interes is to achieve a system that can provide Sybil protection for voting systems. Which is the reason Tor cannot be used with USPS, since one could create millions of colluding evil nodes and ditch the system. I limit it using IPv4 because it is very easy to enforce an homogeneously distributed network controlling the maximum number of nodes/votes per IP. This limit will grow as the IPs are filled with voting power.
I already have the Sysbil protection implemented and the network of nodes running exchanging encrypted traffic about consensus. The only thing I have left are two things:
onion routing (or a faster alternative that doesn't exist but I am researching), chaff traffic.
...and probably more considerations. I am not expert in anon overlays, but perhaps we can brainstorm so I can become one : )
Thanks for reading
