I've used SourceGuardian, too, but I think I dropped it due to the fact that it caused more problems than it solved. In the end I thought, pssh, if people want to steal my source code, let them go for their life. Though Bluesaga (Bless him) will tell you a nightmare-like story of a system of mine and Karl's he bought from Sammy - safely encrypted with SourceGuardian. We still giggle about it now! And even those me and Bluesaga are good friends now, I'm still holding him to ransom over the source code :) !
The problem with these encryption algorithms is that they are required to be reversed to be interpreted by PHP. The individual who has the files that the encryption requires to be able to decrypt the code, and the encrypted files themselves, have all they need to decrypt the encrypted source code right there on their server. It's not like MD5 or SHA1 where the encrypted items do not need to be reversed. And as you see they need to be decrypted every time they are executed, so yes, they're easy to crack, but the speed to decrypt them is also a big drawback and a factor that should be taken into consideration.
