Mike, You can transfer your DNS servers to a DDNS service (they run very short TTLs). Then, if the shared hosting service lets you run a DDNS client, you can periodically GET the main site's home page by IP address, and if you get no response, run the DDNS client to change your A record to the backup site. I don't know what kind of access you have to the hosted server, though. If you can't run this yourself, there's this hosted service from TZO, one of the DDNS vendors:
http://www.autofailover.com/ It will do exactly what you want; monthly cost is $29.95. Notice that they're offering the same service for e-mail, which is pretty silly (unless I'm missing something mind-blowing).
