for eg. a 'hub' server containing only data on the variant versions
could send HTTP 'moved temporarily/permenently' headers redirecting to 
other servers. Much like the system for general web
indirection. I'd need to check the HTTP/1.1 spec to see if redirects can
be w.r.t. particular variants of a resource, but this sounds
feasible in principle.
