There's alot to read, and I've scanned a fair bit of it.  No one seems 
to have tried anything as ambitious as what I have in mind, which, is 
given all the preconceptions and experience available, come up with a 
best expected strategy.  There are fairly straightforward recipes for  
doing this, but I don't think anybody has actually tried them.  What 
people *have* done is to use profiling to identify areas for increased  
scrutiny, but with only limited success.
