OK, for those who have read my posts, you know that I'm by far the brightest person on this board.  But am I to understand that the "tigerlink" has already been built?  More than once?  Even if we don't own those machines, the next one should be gravey.  I thought we were building it from scratch, but it's been tested and proven?  That sheds a whole new light on things.  Very cool!
