Seems like a good recruiting pool. > 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.)
