Jeff,
The reverse DNS has to be managed by the people who assigned you the IP
address, normally the ISP. They control that range of IP's, and so by
setting up a reverse record for your domain they are confirming that you
have a right to use that IP address. By definition no-one else can set up
the authoritative reverse zone. Anyone else (like your website hosting
company) can try, but since they are not authoritative for the IP addresses,
no-one will ask them.
If your ISP won't do it, you could as you suggest forward to a smarthost
