This message is for MMC.  I would also appreciate it if this were added
to the MMC agenda...

There is a proposal in T13 to obsolete ATAPI overlap and queuing
capabilities.  This capability is different from the ATA overlap and
queuing capability found in the ATA queued commands.  ATAPI overlap and
queuing was written into ATA/ATAPI-4 back in 1998.  We would like some
input to help us better understand if this capability is implemented or
used in ATAPI devices. =20

My friends and I were on a beer run and noticed that the cases were
discounted 10%. Since it was a big party, we bought two cases. The
cashier multiplied two times 10% and gave us a 20% discount... and then
he voted
