Thanks, Will. This is *excellent* information. While I may 
still be going crazy, at least in this I feel fairly sane. 
I've swapped to yet a third DSL box, changed the patch 
cable, and reset the switch to which this connects before 
going to my firewall. Tonight, performance is right where 
I would expect it: 1.3Mbps down / 370Kbps up. I'll see 
what happens in the morning.

For just a few $$ more than Verizon, I can get Covad, 
which would (hopefully) switch me to their router upstream 
(not to mention the overall better experience I've had 
with Covad service for clients in recent years). FIOS is 
due here sometime around 1Q 2008, if the scuttlebutt I've 
heard recently is correct. That would, of course, resolve 
a myriad of issues.

(Sorry for the OT discussion, everyone.)
