i have a prototype for a resource discovery fs.  each server that
wants to participate runs a small fs which gathers ldap-like info
about the local system.  each server posts the root of that file
system to a main aggregate which is listed in ndb for the local ipnet
(domain).  a user mounts either a the node itself or all of them via
the aggregate.  aggregates themselves can be aggregated for
cross-domain resource discovery.  run 'ls' and you find out which
nodes are alive, 'cat */load | sort' and you get the one that's least
busy...

it's not anything big, but then again Plan 9 doesn't easily lend
itself to big and complex solutions for trivial problems.
