You raise a very good point.
We are upgrading our national bandwidth next month, and with some BGP trickery, our caching will only apply to international websites soon - meaning the CDNs can be relied upon more and the cache can be more efficient by caching only internationally hosted content.

I appreciate the need for caching, but I don't understand the "transparent" portion of it. Wouldn't it be better for the client device to be aware of the cache so that it can bypass it if necessary? It appears that it's possible to inform the client of the proxy details via DHCP option 252, but as far as I know no ISPs do this. Are there technical issues with this sort of configuration?

You can provide an option 252 in the DHCP response to the customers router, but the router itself runs a DHCP server and probably wont pass that information on to its clients, as it would break locally hosted websites such as if you had an intranet running in the office (like sharepoint)

Also there is no guarantee that the client will use the information provided by the DHCP server.

If its done transparently (and right) it means there is no configuration changes required for the client.

Interesting. I guess that I'm a bit wary of transparent proxies since I was a long-suffering TelstraClear customer before I switched to Maxnet. If Maxnet is proxying then it's being done properly because I haven't had a single issue.

No proxies, no shaping, only local Akamai, Google Cache and a really silly amount of available bandwidth :)

And from what I read... google cache isnt really a proxy style cache - its a CDN system?

I believe that that's correct; it essentially acts like another server in Google's farm. There is no "behind the scenes" redirection to your ISP's servers.
