I am not doing that. Have no time, and, as I am moving to other group inside MS,
soon will have no large servers (that can be used over weekend).

I beleive that for 6-man tables you have to use much more efficient backward
algorithm developed by Stiller (I beleive all others used forward algorithm, as
it is simpler to implement and debug). Also, 8-10Gb of RAM will be a great help,
otherwise you'll have to use less efficient disk-oriented algorithms.

And the latter means that you have to use 64-bit CPU as well as 64-bit operating
system.
