Hm, Thinking about netdb a few days ago in the context of a CDN application.
Has anyone looked into or used the TCP_INFO data available in Linux?
It has a bunch of seemingly useful metrics (RTT being one of them, others
include TCP retransmits/unacked/sacked/etc stats) but I haven't yet written
up something quickly to see whether the returned stats matter.

It'd be rather nifty to grab statistics after short-lived connections - and
periodically on long-lived ones) to build up a map of potential 'best'
paths to clients/servers. It might also be good to have the statistics available
for raw logging in case people are interested.
