So, I did this last night and basically followed David's advice. I
pointed GoDaddy at ZoneEdit, populated the ZoneEdit A Record with my TWC
dynamic address and an MX record pointing to Google. It all works
fine. I created a CNAME to point mail.mydomain to my Gmail dashboard, too.
Also, there was some question about ZoneEdit updates from routers. I
use DD-WRT, which provides in-built support for DynDNS, ZoneEdit, and
about 8 others as well as a custom field to craft your own URL.
I was stunned how quickly the DNS changes propagated, too.
