I agree that some things should not be open source, but at some point,
however obfuscating the source seems like the wrong way.  In truth most
homes, and all cars, are trivial to break into. Yet we still park on the
street relying on our neighbors to respect the law. In the same way, a
software license should be enough to stop theft.

Further, there are daily calls in newsgroups requesting decompilers to
recover lost source code.  I am comforted knowing that as long as it runs I
can get it back.

I trust my users to respect my rules for software I develop.  Perhaps for
widely distributed projects Python is not the proper choice.  But no single
tool is always appropriate, and for times that one can expect some level or
honesty, Python works.
