Would be very difficult right now but never say never in the future, similar technology to that which allowed the Guildford trials would certainly be able to select bandwidth and indeed level of restriction in terms of age limits and content on pages.
The question is though that until the current web cache platform is absolutely stable and is as good throughout the country as it is in the real quality areas I think there are more important things to do than start finding more jobs for the hardware to do.
Let's concentrate on getting the existing platforms absolutely right first eh? Caching running smoothly will significantly enhance the customer experience. Going by my own experience on cable caches where I was were beautiful, browsing an instant experience virtually all the time but some aren't so lucky.
Am sure that plans are afoot to get the caching platform ready along with the network for future proofing while the cash is flowing nicely. I hope this is something that can be incorporated in the future.
Course I could be completely wrong and it could be in trial already
