Sure.  A route-reflector-client does not know that it is, so it can 
have "downstream" rr-clients just fine.

It will delay convergence further, of course, if you have to walk a
longer chain from local market router -> local market RR -> global RR ->
local market RR -> local market router, so it might not be the best of
all designs...

Maybe have all edge routers peer with the global RR for faster convergence,
and peer with a local market RR for local optimum routing?
