Hi, I am researching using zope as a framework for a product that I am going develop and sell. I will develop a python product for zope. The product will not be open source, so I will only be distributing the byte code .pyc files, and not the source. However I understand that it is possible to decompyle .pyc files back to the source....although I don't know how difficult this is to do successfully. Are there any tricks that I should know about to make this any harder? Basically I want to know if anyone else has used zope for a commercial product b4, and how they did it. Is there anything in particular that I should know about. Should I just rely on a good software license to protect my code? Also...are .pyc files as platform independent as .py files? Any info appreciated. terry -- Terry Kerr (terry@adroit.net) Adroit Internet Solutions Pty Ltd (www.adroit.net) Phone: +613 9563 4461 Fax: +613 9563 3856 Mobile: +61 414 938 124
