Bandwidth is the biggest issue, and most hosting services sell more than they expect you to use so even if you use what you're alloted, they not happy about it, and many will want $5-$10 per Gig when you go over. Another key is to make sure you have your own domain name. That way, even if you switch hosting services, you've still got the same url and e-mail addresses. I was Gonna start a thread next week, but if you could get your BW for less than a buck a gig, would folks be intersted? I'm launching a hosting service, and it looks like I'll be able to sell 96G over a six-month interval (averages to 16G per month) and 800Meg storage, for just over $94 (billed every six months.) Still typing up TOS, FAQ list, etc. but pricing is pretty much set now.
