If a c^Hexpirefs is actually written then it should be possible to design
it generic enough for such uses, too.

For the system that I described in my reply to Adam Olsen I would have
rather chosen an order like the following:
(0) Decide whether this design is really a good thing (if it is not then
    ignore the following and start all over from scatch!) :)
(1a) Port some proxy over to the Hurd
(1b) Write a httpfs-translator (possibly based on some existing browser or
     proxy)
(1c) Write an expirefs-translator
(2) Change httpfs so that it works nicely with expirefs (if it's based on
    a proxy then part of the code should already be there)

I wouldn't even expect this approach to take much longer to complete than
yours, and one big advantage here is that the three first steps can be
carried out in parallel and have all a useful result in themselves.

But: as I'm not likely the one to implement this system I'm also not going
to complain if it's done otherwise :)

Lars
