[Nix-dev] Mirrors

[Pjotr Prins]

For some packages a mirror would be nice - as either they are changed
too often, or not often enough. What is the policy here? Can we
provide two URLs? The main one and a fallback if the main goes out of
synch?

Does NIX have a source mirror for that purpose? It is important for a
stable version.

How do sourceforge dynamic download URLs work? Do we have an example?
