There's definitely a huge demand for this, and not just on the home PC level, either.

I do the same sort of thing, but for small businesses. I recently installed a wireless LAN and ADSL router for a company that had everyone using separate dial-up accounts for each laptop. Reduced their bills, sped everything up and they're vastly more secure than they were before. For that, they pay me GBP several-hundred per hour. And it's worth every penny to them.
