ATM is a fine edge technology for lower speed access.
Ethernet is inherently "multiaccess" (can you say CSMA-CD?)

Interoperable MPLS from hundreds of vendors? Yeah right.
IP on the other hand, has been implemented on everything
from x25, ham-radio, Frame, ATM, leasedline, avian carrier,
wet string, lamda, and many other "underlying" media. I
hear seismic waves are under test.

Overprovisioning solves nearly all QoS concerns. There are
very few QoS requirements.

Reassure your exchange clients that you are -NOT- in
direct competition with them.
