A couple of things I have noticed:
It seems that many files are missing in the Linux distro when compared with the Windows files.
Also looks like the firmware upgrade option is unavailable on the Linux version of FrontPanel 3.0.
It would seem that if you are using wxWidgets for the FrontPanel GUI you should make this open source and allow others to help out with the updates. You shouldn’t have anything to hide in this area.
The Sample files using wxWidgets are out of date and will no longer build on a standard Linux distro. The newer libraries seem to have a wrapper around chars in order to fit their new classes.
