The Greenspring-IP plus HiDEOS is running suprisingly well.  The hardest
part is figuring out how to deal with the TI chip on the IP board.  The
DOCs on it are written for a genious-level GPIB hacker (I am not one by
any measure.)  I have run sustained load tests on multiple-devices hooked
to the IP board under HiDEOS.  I have been recommending it over the NI
boards to users here.

The code for it is quite simple.  However, I do not recommend starting
from scratch if you want one to run in your "CDI interface".  I HIGHLY
recommend using the stuff I wrote as a road map to develop your own.

As far as I know, nothing has been done for LabViews.  A while back I
talked with some guys here at ANL that were interested, but nothing came
of it.  Perhaps someone else has been made progress on it.
