Using the dependency browser 'Discovery' appears to depend on all of these packages: #( 'ApplicationBase' 'DynamicBindings' 'TimerDaemon' 'KomServices' 'Rbt' 'OSProcess' ). Inspecting the code it looks like we could get rid of OSProcess which is only used to discover the local IP address. This still leaves on the order of 3000 lines of code which is a bit much for my taste (I'd suspect the actual code needed would be more on the order 300 lines), but might still be worth it if we get a robust local discovery. Worth a try :)

I found a way to get the IPv4 address but it still does not work. I
can't seem to find why it does not work so I guess
it will have to wait...
