I have been trying to think about this a lot. Not much good I suppose-- for a while I tried to think out the concept of a new protocol. A reverse HTTP, and opt-in push type of mechanism where the publisher maintains a list of subscribers and pushes the data to listeners running on the client machines. This, of course, has many problems-- addressability, trust, who controls the opt-in system (to repel the spammers), to name a few. All of these are solvable-- addressability with p2p, trust with certificates, control through trust-- but it is sloppy and not using what is already built out. Because of this I went back to "subscription"-- we use it to describe feeds but I think it is a misnomer. What we really have is HTTP automation scripts masquerading as subscription services. If that's all, then why not just insert a middle-man that can be repeatedly pinged and let the bank push the data to the middle-man? Oh yeah. That's how POP works. That's what we are trying to get away from. Ah well, Jeff Rafter
