Well, actually what I was thinking was that there are often
performance advantages in common operations to having everything in
one file.  Cf. the "Linus laughs last" Mercurial-is-faster-than-git
threads.  That lasted only until Linus came up with a packed format.
(Granted, for Linus it wasn't that easy because he needed to convert
the git DAG into an efficient serialization, and a similar issue might
apply to Darcs.)  I don't understand slurpies, but I wondered if you
couldn't slurp a zipfile as easily as you can a directory by wrapping
an appropriate library.
