Cool.  Sorry I haven't been doing much recently...been kinda busy.  
I've started doing some work for the Oulu University Secure Programming 
Group (http://www.ee.oulu.fi/research/ouspg/), which is good but busy.

But if you want to bounce ideas off me, then just send em my way :)

Yeah, I've thought about this before - the trick is figuring out a nice 
clean way to specify it on the command line.  The actual code part 
should be trivial.
