hrm. than email? even a casual reading of this list will show a ton demand to make it more complex: message queues, private subscriptions, authentication schemes, opaque body contents, additive relays, etc. all things part of SMTP/email. it seems unlikely that it will be able to remain as simple as it is if it achieves widespread adoption. > and most importantly, actually exists. As far as I know, the SMTP-based > system you're describing is 100% hypothetical. i'm talking about using simple email and, instead of letting mail spool, configuring 'stdin hooks' instead of 'web hooks' which all mail daemons provide a simple configuration for and every perl programming sysad in the world can administer and understand - because they are already doing it. let me put it another way: what major real world technical advantages does push have over programatic subscription to url-name based mailing lists and configuring programs which read on stdin to receive mail (rather than letting is spool). what major real world dis-advantages would it have compare to such a system. for the record, i've moved a lot of message around the world using this paradigm and have found it to be ultra robust, scalable, simple to write code for, simple to maintain, and simple to debug. i've also maintained many varieties of push based systems and found them to be massively painful in production due to the eventual real world requirement to be aware of network issues on the receiving end - aka retry logic - something which email based systems handle like none other. i guess i really do not understand how a mega successful push system would be technically superior to having a bunch of machines subscribing to email lists and reading email instead of humans doing the reading... in case people are not aware, there is some really interesting application development in this space: http://lamsonproject.org/ regards. -- -a -- be kind whenever possible... it is always possible - h.h. the 14th dalai lama
