Yes you're correct, wideview is for views and widefs is for instruments and external FS programs that use FSUIPC
I looked around some on the PSS website, but I couldn't tell if you can run the extra panels over a network. If you were able to, there would most likely be an exe file for the different panels like the FMS and overhead.
I have used widefs for the FreeFD glass cockpit software (http://freefd.homelinux.com/). To get it to work you start FS then start wideclient. The white screen would show and it would say that it is connected. Then you could minimize wideclient and start one of the glass cockpit programs like the ECIAS. So once the client is connected, you can minimize it and forget about it.
Like I said, I've never used PSS 747 so I'm not sure if you can run the panels on other computer. Maybe running 3 video cards from one computer is the only way to do this. Any one else have any input?
