That's another option. I'm very lucky. Here in Anchorage, the cable 
provider (GCI), is totally OK with people running servers as long as 
you're not selling webspace or email services (Your home business is 
OK). They deal with abusers on an individual basis. They also do 
network scanning looking for bots and will put a user on security 
block until they fix it, but I've never known anyone who actually got 
blocked. I wish more ISP's had that attitude instead of trying to 
screw subscribers out of more money just to run their mail or 
website.
