You can limit the bandwidth per virtual server, and then juggle with the
bandwidth for each request. Per-process limits have beeen talked about,
and distributed limits might be available when the new distributed caching
system I'm working on takes off (stress put on _might_).
It hasn't been tested on busy servers that I know of. Would you be willing
to experiment? It could be interesting..
Be aware though that performance is going to take a hit if you're using
bandwidth throttling (almost to roxen/1.2 levels) because then I/O would
be done in pike (as opposed to C). Also, expect your RAM usage to
increase, especially if you're serving large files (the subsystem is
somewhat unoptimized, memory pressure systems have been in the talks but
were never implemented).

Interesting indeed. <grin>
