Heh, or perhaps a syntax that's often maligned, but extremely well
defined, very flexible, and one that you can parse unambiguously with
tiny parsers ;>

   (atime 49228382)
   (ctime 33929322)
   (acl (read-permit "foo" "bar")
        (read-deny "someuser")))

could be tranlated straight to a a "hash tree" for perl/python:


etc., and you could handle the binary data separately with
length-prefixing, i.e.

("/foo/bar" ...)
[~230K binary data for bar here]

In any case, I agree that a text format is a good idea.
