I'm sure most of the issues could be solved economically by just charging from a new "higher" service level where the old one theoretically was and charging an amount that makes is financially viable to have those 1% on it. Forcing out 1% of your customers can't be good word of mouth advertising, esp. if those power users probably like to brag to all their friends when their service is superior.


Personally I don't currently run any commercial services at home, nor do I use a particularly large amount of bandwidth as you can see here from my router: http://mrtg.ggxtech.net/snat.html (about 8k/sec continuous average).
But I am willing to pay for the commercial service on the off chance that static IPs and unlimited/unblocked connections might be useful to me at some time. I'd much rather have an SLA than a marketing promise any day.
