Fascinating thread.  Thanks for posting that link Andy.  I agree with some of 
the posters who wonder about the value of using LabView.  

Given how far Lazarus (Free Pascal) has come along now with the "Write Once, 
Compiler Anywhere" philosophy, it may be worthwhile to look into doing what the 
author of the Labview project has done but with Lazarus.  It would allow the 
user interface to be compiled and run on PCs, Apples or Linux boxes.  

The interface done in shared memory as described by the user Rienhard, and the 
user interface passing that information as either Ethernet or locally into that 
same shared memory model.

Bu I might be all wet here.  I don't know enough about how LinuxCNC works to be 
able to even know if this would work.  I have been using Delphi on Windows 
since it came out and I'm very impressed with Lazarus.  I've written small 
Lazarus sample programs on a Windows machine and recompiled and run the same 
application on a Raspberry Pi, BeagleBone Black and the LinuxCNC box.    The 
only issue has been which version of Lazarus as the platforms aren't all at 
exactly the same point.  The PC and LinuxPC versions are further ahead of the 
BeagleBone and introduce features that aren't available.   The Pi is a bit 
further than the BeagleBone.
