....there is nothing to stop anyone pulling either of them apart and reconfiguring it for their own purpose or stealing the algorithm code.
I am not Muse savvy.. tried it..oppose allowing Adobe to control anything - so binned it about a week after it first came up for free beta testing. I know Dreamweaver and the extensions.
If your widget as potential.. than why not market it as both a Muse widget and a iBA widget, Bookry and others seem to making big money - maybe they or a similar outlet will market it for you.
Better still, offer it to Apple, more good widgets in iBA would be welcome.
The magic is in the algorithm it uses to perform a specific task and that is where the value is.
Apple seem to have success in litigation with various device makers who purloin code.... buts also proof that those who can.. will never be stopped from data/code theft.
Good luck with your book and your widget.... maybe when its available you can add a store link to this thread... I would like to see it in action...
