there are rumors you can export the panels with some tinkering, but what does it give you?
are you going to produce the kites? if yes, cost of this software is the least you have to worry.
you will get better results with trial and error method. at least it seams the method all major brands use! after that they just insert the measurements in this software just to be able to e-mail and cut the panes overseas...
if you don't believe me read their interviews for yourself. there are only handful of real aerodynamic professionals in the kite industry!
