A hurdle or speedbump is the one of latencies:

* e-mail is expected, or accepted, to have latencies of minutes or even
hours. And as the packet sizes of e-mail messages are typically small, e.g.
3 KB, adequate mixing or entropy can be gotten in a remailer by mixing 10
or so messages, repeated several times though various hops.

* Web access is expected, or required, to be fast and peppy...people will
hardly tolerate (i.e., will not use) a site which spends minutes between
actions.

Whether minutes are needed between actions depends on the degree of mixing
sought, and the amount of other messages or Web accesses....

Also, a remailer can be done with *one way" paths, while Web accesses of
course require two-way paths. Two-way paths present oft-discussed hurdles
for anonymity. (Reply-blocks, message pools, etc.)

These are not unresolvable problems, from what I can see, but are typical
engineering tradeoffs, a la the usual:

"Speed, anonymity, interactivity. Pick two."

(Or something like this...)

PipeNet will help. Several groups are sort of working on new schemes. I
have my own thoughts about fixing this problem.
