The best way to "estimate" your bandwidth is to launch :) You can always turn it off and re-think.

What's much more likely to happen is that almost nobody will use your service.

Rightly or wrongly, I dread turning it off once it's launched as much as I dread being out of pocket :)

I'm thinking that's the fear that I'll be getting over first, though, as it seems fairly unanimous that I should should just shut up and get on with it :)
