I too consider not protecting the app at all a valid option.  However,
ideally I would like to have something to deter the more simple-minded

rule quite often - confusing and annoying the army of script kiddies
or attackers who are not very knowledgeable or motivated doesn't cost
you all that much.  The rest you'll have to bow to anyway.

And I too agree that user convenience weighs more than good
anti-copying measures.  Which is why I'm considering, if I can't do
LVL under the free/paid app scheme properly, it might be better to
avoid it altogether.  Because pretty much anytime you use a protection
scheme, you run a risk of annoying legitimate users - and running that
risk doesn't seem to be worth it for a protection that doesn't even
protect very much.

Not being able to obfuscate and hide LVL code in other code is quite a
big deal here - under the particular circumstances (all of your code
and assets live in untrusted environment) obfuscation is your
front-line security measure.  Without it, your security core (the LVL
check itself) becomes exposed and vulnerable.

I'll have to think about this some more and weigh carefully pros and cons.

You've pretty much summed up what I was thinking.
