no problem.  scalability just might be of interest to providers.

i am far from convinced that route reflectors will be sufficient.  in a few
years, just about every dedicated customer will want multiple vpns, some
will want many, and most vpns will cross inter-provider boundaries.

the root mis-design here is that it is telco-style, putting the complexity
in the core network.  this means the core bears the burden of scaling.  the
internet style, smart edges and simple core, scales sooooo much better.
hence my mention of ipsec.

but mpls vpns will sure sell hardware.
