ah. forgive me if this has been covered already (i lost track of
where i was in the thread and probably missed some stuff), but is this
a "binary only" feature, or can i use this for scripts as well?
is it possible to "sign" a "script" such that it can be read or
executed by anyone, but not everyone can use the interpreter for
anything, and the script won't work if copied to a different location?
