I wonder if it would be possible to incorporate a user defined withdrawal rule that, if broken, forwards the coins somewhere pre-determined and alerts you. For instance, the user can define arbitrary rules for allowable outgoing TX from their wallets like: "the sum of the digits in any withdrawal is either odd and the second digit is a 7 followed by an odd permutation of "713" for example ".97731", or begins with a leading 1 followed by a pythagorean triple punctuated with non consecutive primes, like .137435"

I suppose a very simple scheme is there could some precise list of allowable next outgoing TX which are hashed to high heaven somewhere...  If a TX not on the list is attempted the coins go to your fail safe.  Just kicking it around because every day I hear about bitcoin theft.  Ways to increase security should be considered...better and better passwords don't help because sometimes people simply make an error or misplace a file or do not understand bitcoin well enough to take the proper precautions.  

Yet those same people will have no trouble coming up with a "pythagorean triple" to buy lunch with?

That's not the point.  The hacker will have no opportunity for any guesswork.  If they managed to get your pass, fine, but now they have to guess a proper transaction within the entire space of allowed rules I could possibly write on the first attempt to transfer out, or else they fail.  The system trips the first time an invalid transaction is made.  If you make a weird rule, there could be as low as 1/10^6 or 1/10^7 probability they guess it but you'd still have some options when transferring coin.  

If this software existed I would definitely make one of these transfer rules and change it often.  I would buy it shit.  I would pay a bunch for this software.
