There is this "wrapping timestamp" alternative as well, but it's a bit 
messier than offsets from the start of the buffer, and doesn't really 
buy anything on the API level. Well, except in a modular synth with 
lots of "small block" subnets for low latency feedback. That is, 
buffer splitting, but that's still doable - and a bit out of scope 
for GMPI, I think.

So: "32 bit offsets from the start of the buffer."

I guess 16 bit would do as well, but that's pointless (unless we need 
the saved bits for something) and slightly restrictive WRT buffer 
size for off-line and heavily buffered rendering. Then again, large 
buffers can *really* hurt (cache thrashing), so it actually makes 
sense to use relatively small buffers anyway... Oh well.
