As other posters have said, it's probably a bad idea to run your site from home if there's any chance of seeing a traffic spike. Most ISPs will cut you off at the worst possible moment.
The biggest counter example I know of for a site that started this way and ended up huge is Markus Frind's free dating site, Plenty of Fish.
"I was running the entire site off my home PC and ADSL connection for the first 8 months."
(not sure if this is the original site that hosted this interview, but it's the first one Google turned up:
