May be, but _I am here, and you are there, and my friends there are busy
by the other projects -:)_. Btw, I don't like to miss such good idea --
may be, I'll found some way to realise it.
The best place for it, btw, is just existing WWW caches caching _on the
fly_ (as cisco WWW engine).

I know. But remember - it took a lot of time to make _peering
aggreements_, to debug _bgp inter-domain routing_, _control of the
routing by the communities_, etc etc. You are wrong, there is not
_hardware vendor's problem_, it's _policy problem_ for now.
