Obscurity takes many forms, and some are useful, particularly to common hackers, and others are completely useless. There are a number of code walking tools and disassemblers that will rename all variables and function linkages and provide annotated source. Someone still has to crawl through that source, but all the obfuscation is removed. I know professionals that use these tools, not to hack, but to perform security audits on products that they use within highly secure settings. I attended a security conference a few years ago, cannot think of the speakers name right now, but he said you should assume that professional hackers have better tools and larger budgets than you will ever have access to.
