A couple of days ago I had an idea about the Amiga and Linux. Modify UAE to include a X interface to the Linux side while running the GUI on the Amiga side, allow UAE to direct shell access to the Linux side and the ability to have Linux applications commutate with the Amiga via AREXX. Also build in support for native code programs and libraries.
With the X interface running on the Amiga side, it’s code could be linked more closely with the native Amiga windowing systems and it would allow for a more seamless integration between the Amiga and Linux.
