Hi Randy,

Michael Tobis of Argonne (tobis@xxxxxxxxxxx, and I think he's
on this list) has created a modeling workbench with a Java main
program that connects subsystem models together via Globus and
uses VisAD for visualization.  Rob Jacob demo'ed it at SC '98.
It is relatively easy to pipe streaming data into VisAD.  You
can create a thread that updates values in a VisAD Field data
object from the data stream, where the Field object is linked
to a VisAD display.
Of course, it takes some work to get real applications working,
but there is no theoretical barrier to what you want to do.
