Th redirect should of course include some info in the redirect URL
regarding how many times it's been redirected - you don't want to get
into a situation where users are bounced around indefinately.
Personally, I'd go a step further and collect performance data so that
load balancing can make better decisions for redirects. No sense in
redirecting a local connection to a remote site.
<p><p>> Round robin DNS isn't really appropriate as you noticed. Something will

> to my mind really quickly is some kind of new config option to specify a
> list of mirror servers.
> If the client limits are hit on the server, it sends back an HTTP
> redirect with the location of a random mirror (not itself). This should
> be transparent to clients and acheive the affect you want. You could
> also combine with with round robin DNS to spread people over the servers
> Seems fairly elegant. Probably you want this configurable on a mount
> level not a global server level, but it shouldn't be too hard to
> implemenet. Just a config file addition plus some extra logic in the
> main connect loop, similar to what happens on a 404.
