Hsu considers himself a hardware designer. This is what he did at CMU, and at IBM. I don't think he has any interest whatsoever in taking a clever hardware design he did and trying to write a program to implement that design in software so it could be run on a PC. It would be a _huge_ undertaking to do this. Tom mentioned he would write the eval in 1 month given the details of the eval. If he did, it would (a) have enough bugs to make it worthless and (b) be so incredibly slow as to be useless. Because the DB design would have to be kept in terms of its specifications for what it does, but would have to be redone totally in terms of _how_ it does that. Because hardware design domain is different from software programming domain, significantly.
