Question on developing software based on CI

[eluser]internut[/eluser]
Hey guys,

I'm in love with CI. Have been working with it for some time now and things are going well.

I've read over the license agreement a few times. I'm curious what I can and can not do, or need or dont need to do.

Am I allowed to encrypt / obfuscate some of the code (libraries, controllers)?

Not that I want to but can I encode everything if I wanted?

I'm pretty sure I need to state that the software / code / product is based off CI.

Just trying to make sure I do things correctly and make nobody angry and protect what in the end I've put 12+ months into
