Peter,
The question is not whether it is possible to reverse engineer the code,
but what is the incentive for commercial users to buy a license.

It is probably as easy to disassemble and modify a LiveCode generated binary as
it will be to modify a LiveCode generated JavaScript file. Do you worry about
people disassembling your binaries to modify the code it? It would take the
same level of skill to do change the generated JavaScript code.
Take a look at this example -

Sure some dishonest person could spend a vast amount of time to modify one of
your applications but would they find it worthwhile? I don't think so.

Obviously, Peter. Brahmanathaswami and I are well aware of it. The point,
however, is that if you have the commercial license, you're still releasing the
source, but in obfuscated, rather than compiled, form. So, the question
remains, why would one buy a commercial license?

Hi Mark
Surely the difference between the open source and commercial versions is that
under the the terms of the GPL if you distribute a LiveCode generated HTML5
application you must make the LiveCode source available.

Thanks for the reply, Kevin. I'm glad that no CGI engine is used.
I did read that the engine will be "compiled to JavaScript". The website also
says that no plug-in is needed and that the app will run in the browser. Both statements
say nothing about the server.
The website shows "no install" in big letters and states that the end-user
doesn't need to install any software. Nowhere it is said that the developer doesn't need
to install any software on the server. It might help if the website explicitly said that
no CGI will have to be installed and that only the HTML5 files, (text files and perhaps
media files), need to be copied onto a server. Pehaps it is all clear to native speakers
of English, but a more explicit wording of the website just might convince some
non-native speakers who are now reluctant to support the HTML5 initiative.
I still wonder about the closed nature of the HTML5 files. It is probably
possible to write a converter, which converts the JS to something readable.
Even without such a converter, one would be able to download the files and put
them on another web server, perhaps with a few small modifications. Therefore I
too wonder what a commercial HTML5 license can do for a company. I'm curious
what Heather will answer Brahmanathaswami on this matter.
Obviously, obfuscating and licensing are two different things. In my previous
e-mail, I only meant to say that obfuscation and licensing could offer
opportunities that make closed-source licensing worthwhile for both RunRev and
LiveCode users.

It is not a CGI. It renders client side in the browser, without a plug in.
Technically yes, you can look at the JavaScript in a browser. However
given the complexity of it + obfuscation you won¹t realistically be able
to make much sense of it. There is a whole world of difference between
obfuscated/unreadable JavaScript protected by copyright and the GPL, which
requires you to upload the stacks for your entire application with
readable, editable and redistributable code.
I hope this helps.
Kind regards,
Kevin
