After thinking about it, if deemed to be helpful, I can switch
the signature to "\x80kate\0\0\0" and mandate a reserved
0 byte field following it. The actual bitstream format would
not change, only the interpretation of the magic.

I'd then do a similar hack in other headers, which also have
the magic (with a different packet type byte).
