Hello,
for those of you who are interested in doing weird things in Apache,
I would like to advertise NetAirt -- a brand new redirection system inside
an Apache module. It supports both DNS- and HTTP-based redirection,
and can be used to implement Akamai-like 2-level redirection system.
And yes, it implements a UDP server inside an Apache module (although
with a few-lines patch).
As for replica selection, NetAirt can select topologically-proximal
replica servers based to network distance (AS-hops); classical stuff,
such as normal DNS operation (name-to-IP), and round-robin address
selection is also supported.

Comments welcome :-)
Enjoy,
M.
