I don't know about PV-Wave but in IDL there are several ways to do things like
that. You can run IDL as RPC-Server or RPC-Client. It is possible to provide
running IDL-Severs on distributed Workstations over the whole Internet with real-time
data. Another possibility for nearly-real-time purposes is
updating a display program in IDL with periodically checking an incoming directory
for new data in a background task. This way we distribute Radar- and Satellite
images on our Wide Area Network with 10 Sun Sparc Servers and 160 Workstations.
The images are first distributed to the local area servers and the IDL frontends
on the Workstations then check the NFS mounted incoming directory. On normal
use of the network running animation loops are reorganized and updated when
a new image is in the incoming directory in less than one second.
You can get the current state of our online animation solution via ftp:
ftp ftp.sma.ch (141.249.3.33)
cd /pub/idlmeteo/loop-tool
bin
get Meteo_Anima_2.0a.tar.Z
It is in a working state, so there is to much documentation at this time.
