Re: There Might Be An Alternative
Hmm, it pretty much reads like I thought it read originally. The essential idea is to use the IPv4 equivalent of a PBX router at IP endpoints. These endpoints will then be used to interpret specially-formatted IPv4 packets (they have RFC1918 addresses and a specially-encoded Option Word that IS part of the IPv4 spec) to act as extensions. Still have to wonder how these extension packets would get routed correctly, especially since most outside routers are supposed to drop packets with RFC1918 addresses. It's similar to a concept I'd thought about to introduce an extended routing packet to an IP endpoint to tell it to continue routing something internally, but I realized that implementation would not be as easy as it sounds, particularly if a single IP endpoint is simultaneously handling multiple connections.
