Obfuscation is only adding another layer of potential bugs and security vulnerabilities to your program. Please don't do it.
The kind of people who write obfuscation software usually seem very sketchy and non-skilled anyway.
If your code is "great", crackers will go through great lengths to spread it, regardless of whether or not it is obfuscated. If nobody knows/cares about your code, they probably won't, either.
