Yes - interesting idea, but to me not practical and I think 
there may be more of a hurdle here.

Regarding practicality and efficiency this would not 
cut it for, say, being utilized in the middle of a 
record update live transaction.

Well, I think it would take more experience than what is 
needed to write what Ken wrote in his salary example.

Yes - and when trying to use rcabe to tokenize the called table, 
one should get prompted then for the creation passwords.
