cockpitvisit,

I know you've stated in the past that you don't intend to open source this wonderful app because of commingled commercial code issues, but besides the odd misplaced airport location it seems most updates are to the dat files, not the application logic.

Assuming you have some automated way of merging all of the airline schedule data (you must!), would you consider releasing at least that portion of the code/script?

You're doing a great job keeping your app recent & relevant, but as you've stated, this is a side project for you, so it doesn't take precedence in your schedule. Your app could be more useful to more people if anyone (well, anyone with enough ambition!) could gen dat files on demand (i.e. as soon as new schedules are available).
