as you might have noticed, people started to behave 'strangely', and answers are not as useful as they were before. This might be related to "freak" and recent threads, where doubt is expressed about your motives.
Personaly, people who misuse the knowledge of other people piss me off. And all evidence this far suggests you are one of these people. Would you care to explain what system you are trying to design actually will be used for, so hopefully we don't have to doubt your motives anymore?
