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). > > internet - and it have not eny success except a few of pylot projects. > > Compare RealVideo auditory and multicast auditory for now...

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. > > The benefits are obivous though and router vendors are definitely progressing, but as with any technology, debugging and getting the protocols to a usable state, one to which SLA/SLGs can be assoicated, takes time. > > -danny > > > Aleksei Roudnev, Network Operations Center, Relcom, Moscow (+7 095) 194-19-95 (Network Operations Center Hot Line),(+7 095) 230-41-41, N 13729 (pager) (+7 095) 196-72-12 (Support), (+7 095) 194-33-28 (Fax)
