Damn. Forgot the note on compatibility (Blame the time, here in the UK its 4:22AM)
I was basically going to ask, since most entities used appear.fpi, default.fpi, etc., for backwards compatibility could there not be LUA files put into the directory with these names and extension of .FPI to maximise compatibility with old models?
EDIT:
I suppose that will depend on what become of the FPE files?
EDIT 2:
And no, making that image and finding FPI in the newsletter back issue didn't take me 1.5 hours... Honest
EDIT 3: Of the 22 views to this thread so far (that haven't been me editing it) Clearly none have a sense of humour
