How about synchronising all RSS feeds using NTP-synchronized clocks so
that every RSS client in the world polls for updates at exactly and
precisely the same instant, every 5 minutes. Sound crazy?
Let me introduce you to a little-known technology known as IP multicast.
Think about it...

P.S. My company happens to carry large amounts of RSS-like data=20
using IP-multicast. You may have heard of this RSS-like system
invented back in the 1870's under the name of "ticker tape".
Nowadays NYSE, NASDAQ and other markets still distribute tick
data but it is done using multicast. Everything old is new again.
