 I'm not working on MAC's at the moment (or more accurately, my work
right is only concerned with receiving packets, not sending), but
certainly being able to pass along the metadata would be a nice feature.
 For the moment, I'm able to do what I want with my afore-mentioned
custom source block (where only the source block has access to the
timestamps), but I can see situations (in the future) in which I'd like
to have that info passed along through the flowgraph.
 I recall some discussion with the m-block's being concerned with the
performance of the PMT data types - can you address that? Has that been
resolved/can resolved via some technique/won't be an issue with next
year's CPU's/etc.?
 Thanks,
 Doug
