Serving Web from volatile Dial-up IP

I feel like there's something lost in translation here.
How so? I read this as, he has a home net without a static IP (I'm not sure why he's calling DSL "dial-up" but perhaps that's how his telco handles it). Using a VPS, he can make it look like it has a stable presence by reconfiguring a reverse proxy when the home net's IP gets changed by the ISP. His cron job checks if the server can access itself through its "stable name," and if it can't (because the reverse proxy isn't able to access it on the old IP anymore), updates the reverse proxy's configuration over ssh with the new IP. Hacky, but if that's what you have.
yes, it's not be the most elegant (poll is ugly and so is remote filesystem write), but with the least ingredients (dependencies) and few moving parts. An option to choose from.
