	Out of curiosity, can someone provide some pointers as to where 
SACK really helps?  Is this just for high-speed WANs and doesn't help 
on LANs, or is it useful in both contexts?  Also, at what 
speeds/packet sizes does SACK start to become really useful?

	I'm just wondering if there aren't a lot of people who could 
benefit from something like this, only they don't know it.  If they 
were to find out, it might help provide funding and other resources 
to spur development.
