This is exactly the program flow I had in mind. Any ideas how to get
it started? :)
Seriously though, I think the spread toolkit might just be the trick
for the messaging subsystem for my monitoring app. If you know if any
perl sample code I can get my hands on, that would be great - I
haven't had much luck finding scripts using spread on the Internet.
Also, is spread suitable for use over high-latency WAN/Internet links?
Since the monitors will mostly be running on desktop linux boxes
connected to cable/DSL connections, are there any caveats to this sort
Thanks for your input!
