I've signed up with www.reliablesite.net utilizing shared hosting for my ASP.net project.

One major benefit I've already come across is the separate application pools per each website.  Basically, if I hit an infinite loop or cause havoc due to user-error, it doesn't affect my other sites.

Being able to stop and restart a website instead of the web server (as per apache) is one thing I think is an excellent step forward.
