Barb:

I have not heard back from Don, but Peter tells me
that the NCAR node on the Access Grid is under construction
at the ML, so I did a little research on the Access Grid. 

The Access Grid was designed at Argonne Nat. Lab for exploring
"the use of large-scale projection based systems as the basis
for building room oriented collaboration and semi-immersive
visualization systems". It is designed as a "low cost environment 
aimed primarily at supporting conferencing applications, but it 
also enables semi-immersive visualization and in particular, 
remote visualization".

As of spring 2000, there were over 20 sites up and running,
and nearly 20 more sites planning deployment in the next year.
NCAR is apparently one of the latter.

Since I have not been able to talk w/ Don, I don't know the
status of ML/FL communication or vis labs, although Peter
mentioned there have been plans to use the two sites as a
testbed for remote collaboration.

Here is an Access Grid URL at ANL:
