Trunk appears to be unstable; I can't get a successful build happening.
Here's the error I keep getting:

boost/utility/value_init.hpp(70) : error C2061: syntax error :
identifier 'wrapper_address'

Anyway, I see the technique you're using below. I'm going to play around
with your idea, and possibly add some more obfuscation and see what I
come up with.

Thanks so much for the time you spent writing that sample.
