I am sure you are right that these people should have access to plenty 
of hardware - in particular, they should be in an ideal position to help 
with testing/tuning for SSD usage.  But they may not have the time to 
help much, unless Intel is happy to pay them to do so.  People who have 
lots of time - say, a new graduate or someone "between jobs" - often 
don't have the hardware.  All I am saying is that /if/ there are such 
people around, and they are serious about working on md, then I think it 
should be possible to raise a little money to help them help us.  (The 
same applies to existing md developers, of course.)
