It is Coda without the NIH syndrome.

--- i.e., it uses local filesystems for the cache (in *readable* form,
unlike Coda); it uses ext3 for the journal-like and version vector
storage (rather than a special-purpose cache, unlike Coda); it uses (in
the upcoming version) a compact special-purpose HTTP server/client pair
to do the data exchange (unlike RPC2); and it doesn't use a weird
lightweight threads library.

It's also *far* smaller and *far* faster, with drastically lower
resource requirements; and it doesn't have the rather arbitrary
distinction between clients and servers that Coda had (as in, the
distinction was there for a good reason, but, as intermezzo proves, you
can build something with basically identical functionality without
having such a distinction at all).

Nice.
