If you want to design a security feature, you need to offer a threat and risk
analysis, not just the whining of customers.

well, the complete analysis is easy - the solution is not.
currently we have basically no option to reduce access to the system tables. this would be hard anyway as we need those tables for basically all kinds of operations. the problem here is that vendors of appliances don't want people to spider their codes. this is a fact - it is not the idea of open source to do so but bloody reality. in addition to that people are not willing to code everything in C just to hide. so, there has to be a concept to achieve this for stored procedures somehow. i am afraid the source level encryption is the easiest thing and most understandable thing to do.

so, better ideas are welcome.
