I realize it's a bit late to work it into the spec, but perhaps, in lieu of a full granulepos field in the packets, the packet could at least store the numble of granulepos units it contains?  That could be a smaller integer (32 or maybe even just 16 bits).  Seems like that would make it simpler and faster to do sample-accurate seeking.
