This general sort of thing has been discussed...though not 20 years ago! :-0

I don't know about this particular mathematical algorithm, but things
generally like it.

Long before a remailer shuts down, he should certainly adopt a strategy
like this. Sending "his" traffic through randomly selected other remailers
is certainly an option. (Any remailer can at any point insert additional
hops, or even chains of hops, merely be addressing them correctly. Of
course, the "original" (which may not be the real original, of course, as
other remailers may have done the same thing) needs to "get back on track,"
else the decryptions won't work. But this is all a simple problem.

I don't know what gets discussed on the "remailer operators list," not
being on it, but it sure seems to me that remailers have stagnated, and
that some of the robust methods of reducing attacks on any particular
remailer are not being used.
