	This is why some providers (like Verio for example) have opted
for the dual-stack v4, v6 approach.  I expect to see a number of
other providers move this path as well.  There seems to be a lot of
movement in the direction of everyone dumping their voice traffic
on their internet backbones.  I seem to recall seeing Sprint, Telus
and other "traditional" telephony providers moving towards what some
people call a "converged network".

	Transporting their voice traffic within IP or MPLS (using
stuff like the juniper ccc and cisco equivalents).  It's interesting to
see the increased reliance on the internet as a network that can survive
significant catastrophic events and still provide reliable communications
(eg: sept 11, northeast-north-american power outage) for a large
set of people.

	The success of people like Vonage and others in transporting
services across the global IP backbones/networks clearly shows
that the reliability of the network is sufficent for them to
build a business case around it.

	When something new comes along (eg: bgp-5) there will always
be that backward compatability until the edge networks
upgrade.  What used to be a few years lag for them to upgrade is now
increasing as we've clearly seen happen in the software market
(both for pc and routers.. how many people are still running
win95 or ios 11.1 on their older, perfectly "good" hardware?)
