becauuuuse... if soooo... then that's a solution! you get the .idx
file first, you make sure that that's cached (and it's small, isn't
it, so that would be ok), then you transfer it around the network, and
you ask each repo if they can re-create the pack-object from the
contents of the .idx, if they can, blam, they're a seed/sharer for
that pack-object; if they can't, tough titty, they've probably had git
gc run, or had some more commits added, or whatever, and can't
participate, wow big deal, no great loss.
does that fly? :) if it doesn't fly (with --window=0 --delta=0) would
it be easy to add an option to say "oi, gimme a pack with nothing but
these refs, in exactly this order, no quibbling, no questions, just
gimme"? and you could call it "the same as the original" because,
duh, it would contain exactly the same objects as the original.
am i even vaaaguely along the right lines? *scratches head*.
