We are bound by non-disclosure to limit what we say about future
products of the vendors we have chosen for final evaluation.  I don't
think it is any big secret that vendors do have new products in the
works.  IMO- the so called "wall" is not a problem but you need some
heftier routers than what is commonly used today.

I don't like the idea of going into a layer 2 and letting layer 2 deal
with it.  You can probably build a working network either way.
Equipment cost per port is not our highest priority, it is secondary.
Stability and low loss in our backbone is a very high priority.  That
says a lot about why the technology we ar looking at is different than
PSI, Alternet, and Netcom (and maybe a bit different than Sprint too).
ANS charges more for a reason.
