If you say so. ;o)

Quite.  I'd have thought that being a Lessig fan though, you;d have gone
for the ShareALike license. ;o)

No, quite.

I'd venture that on it's own, the time-line listing is not sufficient
to warrant Copyright protection.  It'd surely have to relate to the
content it times, for any Copyright to hold.

Maybe not exactly, however, it does cover the attempt to someone to
force GPL on the output from your program script ( that a user is
running.. )

GNU emacs is GPL.  A text editor with a Lisp based interpreter at it's
heart.  If one were to write a presentation or short story or similar,
using it, I doubt one would be required to release said work under GPL!
( User's choice of course ).

swfc script is a script language in it's own right, one released under
the GPL.  It's format allows the swfc compiler to turn it into an swf,
Action Script included.  What is produced, bearing in mind certain
restrictions, is again user choice as to licensing.

There we disagree.  It is merely compiled Action Script.  Nothing more.
Where is the derivative bit?

Are you referring to the swfc scipt or the ECMA script?

I've not tried it of late, I should go look.  Anyways. maybe by the time
it has been developed further, you will have moved away from your
dependence on Flash swf format!!!
