Yes this is true.  However, you have some Broadband ISPs (RR, Speakeasy) 
that will offer additonal ips for an extra fee without having to pay for 
business access.

Many broadband ISPs also do not offer business access to residential areas.  
Everytime I've asked one, they couldn't give me a good reason why.

Exactally.  However, that's why you have a "Service Level Agreement."  Can't 
really win a lawsuit that easily without on, one either side.

I don't know if many broadband providers offer a SLA for business 
connections as well, unless its something more economical to provide a SLA 
for, such as a T-1.

I do know when I signed up for a business cable modem once, it said in fine 
print on the contract "You will not hold RoadRunner responsible for down 
time due to network issues, etc."  I'm pretty sure most broadband providers 
stick a clause like that into the contract.

How could 1% of your users suck down %50+ of bandwidth in such a scenario?  
Even though they are running NAT, they only have one address, one MAC 
address from the cable modem, and one system doing the rate limiting off of 
that ip/mac address.

When someone's running NAT, the bandwidth is distributed between the users 
behind the NAT device.

If someone's assigned 512K, they can only use up to 512K, be it one 
computer, or several behind a NAT device.
