fyi,
Metalink (http://metalinker.org) is a spec for file sharing systems. A
doc in its XML format points to locations of a given file, potentially
across various protocols - http, ftp, bittorrent etc. If you have a
look at "Who's using it?", you'll see it's pretty widely used both by
publishers & consumers.

For an example, see:
http://cdimage.ubuntu.com/releases/8.04/release/ubuntu-8.04.1-dvd-i386.metalink

(that only refers to one instance of the file, but you should get the idea)

If you check the source of http://metalinker.org you'll see it's
GRDDL-enabled - well, kind-of, I got distracted before getting
everything running smoothly (the XSLT should be pretty close, but the
W3C GRDDL service throws a peculiar error).

I reckon it might offer a potential route to offering fallback sources
for schemas etc.

Cheers,
Danny.
