Darcs send packs data much tighter than darcs itself does, and the results
are highly compressable. I have a HEAD tree, obtained with "./darcs-all --extra
get --complete" (you're not misreading that); darcs sending everything (incl.
subrepositoried) into an empty repo, and 7zipping the patch bundles, produces
a single 28mbyte file containing the entire history of ghc+extralibs. (I still
have the file but can't share - 10mb webhost quota)
