My "(cheap) cable modem for general browsing" provider wouldn't even
delegate RDNS; they'd only put PTRs in *their* servers. Swap BGP
routes with them? Swell dream.

This has become a common strategy: the cheap, fast, commodity service
for the most-of-the-time that it's working and the most-of-the-stuff
that it works for combined with the expensive and slow but reliable
and full featured service for the mission critical apps. One of these
isn't going to come with BGP and a PI prefix, and the technologies we
deploy are going to have to deal with that.
