Fielding On Rails

To distract me from looking at too much production Akamai data, Greg
gave me an Untangled posting on notification architecture. I was
considering a mental picture of what Roy means by "inverse economy of
scale" for PubSub. I assume he is referring to cost function C(n,m) of
consuming clients n and rate of messages m and that cost increases
versus decreases with HTTP REST style architecture along the n and m
domain. I also think that as n increases C inflects at certain points.
I will have just wait for Roys upcoming posting.
