Just the other day I've been having this hallway conversation where
I tried to make Plan9 sound as a solution to all the problems
(excluding world's hunger, perhaps) and the question that made
me write this email and humbly ask for your ideas was this:
"Well, it seems that Plan9 is really good about making *use*
of resources, but how does it help you *discover* them?".
Well, I, for one, didn't know how. Of course we have stuff
like ndb(6) (and DNS) but that's not a "resource discovery"
worth writing home about. srv(4) comes closer to facilitating
it, but, alas only within a particular server.
I guess my question is -- is there any research going on
on how Plan9's philosophy could lend itself to this problem?
Any ideas ? Implementations ? Anything ? :-)
It's not that I'm looking for something particular (rather than
having an exciting thread here :-)) so I'd appreciate all
the feedback.
Thanks,
Roman.

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.

nemo and gang's Plan B work perhaps? http://b.lsub.org/ls/papers.html

there is an RFC for a RLP [Resource Location Protocol].
looked like junk to me, but maybe i missed the point?

inferno has virgil, tho it's rarely used in the wild.
i find it good for "anyone out there got a /dev/mathlink?".

The Plan 9 derivative that I'm using, which we call Plan B,
has all its services `discovered'.
For example, /bin comes from
mount -V /bin/!$cputype /bin
BTW, this beast can also redirect some I/O devices (eg mouse)
for usage with remote machines.

The page in http://lsub.org/who
is gathered from different sources, and we see that as /who.
We use directories instead of other std for exporting information.
The thing seems to work well.
