I'm aware of SDS and I looked at his stuff many years ago and even
attempted to contact him, but all the reasons escape me now, but I think I
recall that some of what he was doing wasn't really applicable to my
project and some of his performance claims seemed to be overly optimistic.
However, I just looked at the page you posted and it seems to be new and
worthwhile info that I don't remember reading.

  Looking at the dates that he posted it though, it is a sobering reminder
of how fast the years have flown by....

Once I'm back in the air and looking for places to fly, I think I may just
pop over the mountains and pay him a visit.
