Re: Anonymous WWW proxies

|  + Chaining would be a imo good idea (ie cli <-> anonproxy1 <->
|    anonproxy2 <-> ... <-> server) but how would you manage to tell
|    your favorite web browser to add in its header something like
|    Http-Proxy-List: anonproxy2, ...
|    An alternative would be to have a database of avaibale (running)
|    proxies and that the proxy itself randomly choose a next route ?

Doesn't most of the browsers support a "firewall-proxy-mode", where
all queries are sent of to a special daemon, that forwards the query
on. This would probably be the place to add the header-munging.

How do you plan to get the reverse-path working? Having a
encrypted/chained return path in the request?

Encryption speed isn't all that an issue always. I'm planning to do an
Mbone encryption gateway, (RSN). I will precompute a cryptographic
mask during idle cycles, that can be XORed together with the
clear-text packet when it arrives. I expect it to reduce the latency
quite a lot. (This might not work, since it assumes the key distr
problem is already solved in good time before the packet arrives, to
be able to amass "precomputational power".)
