Consumer ISPs (usually) bundle four things - DNS, email, usenet and 
passing IP packets.

There is no need for these to be bundled, but bundling them has 
advantages - however the prime function of an ISP is to pass IP packets. 
If they don't pass packets then they are not an ISP.

Usenet, email, and to a lesser extent DNS can all be supplied elsewhere. 
It seems quite logical to seperate these functions from passing IP 
packets, at the very least in the way they are treated under the law.

And how often does that happen .. ?

Not what I'm saying.
