As I mentioned in other threads, jigdo requires that the slices be
available via http somewhere.  The amount if time we have to spin a
snapshot and get it somewhere public for it to have any sort of
relevance is pretty darn short, and trying to instasync a number of
mirrors hasn't gone too well in the past, and those mirrors would just
quickly become overloaded and not able to handle jigdo requests anyway.
(there are those that would just http mirror things instead of using
jigdo).  So for the most reasonable turnaround time, we use torrent.  We
can upload isos in a matter of hours and start the torrent system.
Theoretically I can seed as well as I just did the compose, and we might
be able to seed a few other places that have fast access to the
snapshot.

We'll keep thinking of better ways to deliver the snapshots, it's just
quite difficult to do something with fast turnaround /and/ have a way to
spread the delivery load.
