Schneier: ISPs should bear security burden

Hi,

maybe this is an OLD topic, but the problem is "what
is security? " or "how to define a secure internet
access service ". E.g. should ISP respond for managing
application transmitted across its backbone? if so,
how to define "standard" appliation model while
keeping internet a flexible platform?

Could we maintein the scalability of IP network while
keeping it secure & high performance?

To business consideration , would people pay more
money for a limited, "secure" internet access service
while his/her child is able to visit those Nude
website?

So, IMHO, it's a good idea but it's not a feasible
proposal.
