A day of protecting PHP code

So, spent a day protecting some of our code today.  We've used a cross between some in-house obfuscation on some files and using SourceGuardian for protecting the core files - therefore leaving everyone with the ability to alter the code and design without compromising our intellectual property. It seems to have worked quite well. SourceGuardian is a PHP Encoder that runs on OS X, Windows and Linux.  I purchased the OSX Encoder and it works just like any other Mac app.
