I'm not sure we're on the same planet. Please help me out here.
I can think of a few applications that have agents, gatekeepers, proxies, and gateways, mostly resulting from the imposition of firewalls or authentication systems, or from legacy applications like imitating the telephone system in a data network. The only one that *requires* any kind of gateway, to my knowledge, is H.323 teleconferencing, which represents a paltry fraction of traffic according to most current measurements. Anything else (75% of Internet traffic is http or FTP, most of the rest is mail, on private LANs applications like NFS are pretty common, and even SIP can be done without a gateway between consenting systems) could be hooked up in separate systems on a LAN and made to work without any such signalling at all.
Could you be more specific on what QoS signalling is required by the world wide web, mail, FTP, common ERP applications like ERP and PeopleSoft, calendaring, and so on? If not, could you be more specific about what "all" applications you have in mind?
And could you be more specific about what issues this proposal is addressing that have not already been addressed in de facto standards and deployed in operational systems? It would be very nice to understand what you are preparing to ask vendors to do, and whether operators are interested in deploying them.
