Ulf, gproc looks like it could be used for my many redundant requests/only
do the work once problem?   As long as I can normalize the request to some
type of term to act as an identifier I would be able to discern if work was
already being done for that request and if so I could use it to satisfy
multiple clients?  This is a little more transient than "looking at a
request and forwarding it to the right server" as these are short lived
"servers" but it seems to be the same idea, no?
