Thanks for your interest in Geowall.

Here at EVL, there is no formal interconnection of the hardware of the
Geowall with the AG.  Any integration of the Geowall with the Access Grid
at this time is strictly via software.  The only Geowall application
created at EVL which can be integrated with the Access Grid is
ImmersaView.  Purdue University has also created a Geowall app that works
with the Access Grid which I will describe later.

For SC Global 2004, I created an application that integrated ImmersaView
into the Access Grid 
The integration of ImmersaView into the Access Grid occurs with making a
shared application that takes care of setting up a collaborative session
within the context of the Access Grid.  It should be noted that
ImmersaView provides its own collaboration capabilities.  This Access Grid
shared application is named ImmersaView Launcher ("launcher").

ImmersaView Launcher allows all sites running the shared application to
simultaneously start viewing a model that everyone previously agreed to
running (either verbally using the video/audio channels of the Access Grid
or via some instant messaging client).  The launcher has the benefit of
allowing ImmersaView to run on any computer without modification as long
as that computer is running a lightweight Python XML-RPC server (in
addition to some other supporting files).  This XML-RPC server process
requests from the Access Grid venue client that will start batch scripts
to configure ImmersaView to begin displaying the appropriate 3-D model
files.  If you want to learn more about ImmersaView Launcher, please

A related project that was also demonstrated at SC Global that utilized a
passive stereo display like the Geowall was the integration of VRJuggler
(http://www.vrjuggler.org) into the Access Grid as a shared application. 
Here are some links involving the project:
