Don't forget you'll have to have DSL CPE in every room; that's why most
places use Ethernet in the first place.

You don't state what kind of density you require, but several vendors
build GE aggregation devices.

Unless something's come out recently I wasn't aware of (likely), nobody
can SAR at multi-Gbit speeds.  In any case, why SAR it to ATM at the
head end when you already have it there as packets?  Isn't that
counter-productive?
