John -
Good post, but a few corrections - XDSL is a 'generic' name for the range of products which include various physical media. ADSL in its current incarnation has a couple of variants as you suggest, mostly differing in the back channel speed (128K in the standard CPQ is backing). CPQ's standard was recently approved by the standards body so that should resolve the compatibility issues. The XDSL standard (and ADSL as an implementation) will go to 8 megabaud forward and 512K backchannel in the next generation of hardware.
The physical limit for ADSL is 12,000 feet from equipment to switch (by comparison ISDN is 18,000 feet) so you are right, there are some places that won't be able to get it. SWBell claims that more than 80% of their subscribers are within 2500 feet of fiber (and the switch can be dropped onto fiber almost anywhere) so they see a large potential customer base.
