Even if it's, in theory, possible, suppose, just as an example, in
between many other possibles ways :
1.- your main stack is password protected ;
2.- this stack contains substacks protected by randomly set passwords ;
3.- the mainstack herits from the substacks stack's and/or card's
scripts by activating them as front and back scripts...
No sure it will be a piece of cake to rebuild all the stuff needed to
get the stack cracked and runable at the same time...
I remember an hypercard stack i did so uncrackable, uncopyable, etc...
that i could never restart it until i took together an old unprotected
issue of it and the source code of the protected stack to build a new
one... In about protecting code and apps, the key features are in the
design, lots more than in the technical tasks...
