Caches seem to be the majority of concern in the last 3 to 4 weeks, I
doubt anyone would disagree they can be useful just like web caching can
be useful.

The question is does the pros outweigh the cons?

If shared caching at the ISP level is abandoned in favour of moving them
closer to the end user, either on their computer or on the LAN but isn't
accessible usually from beyond the LAN, would that not solve the
majority of concerns currently being expressed?
