First of all, ossein isn't exactly gelatin. It is the organic residue
(primarilly collagen) left after the mineral content of the bone is
dissolved away, and is the precursor to bone gelatin. Ossein requires
further treatment to convert it to gelatin.
I don't know if there are any particular benefits. I would guess that
there aren't any and would be partial to the use of Knox gelatin for
carbon printing, but then I've been wrong before.

I'm not certain. I guess it depends on the cost, and if you want to
experiment.
Terry King was the guy who was pushing the use of deionized ossein for
paper sizing. He claimed that it worked great and required no chemical
hardening. You might want to take a look at the list archives to see what
has been said about it. I personally have no experience with the stuff.
