except that big routers are not needed for small-isp exchanges.  remember,
an isp participating in such an exchange has only to add the prefixes of
their local peers to their routing, typically a dozen or so.  there are very
successful layer-two exchanges where the peers use what we think of as cpe
routers, e.g. cisco 2501s.  and what's nice is that this is on the right
path to exchange growth.

l3 exchange ponints are a labor suck and are fragile.
