This is very nice, but why are you posting this to john-dev rather than
john-users?  I think this belongs to john-users, as we're not discussing
any source code snippets, etc. here, but rather you have an end-user
usable tool (right?) and you're asking for feedback on that.  (Yes, you
also have a library.)

I suggest that you post the same message to john-users, and encourage
further discussion there rather than here.  This will reach more people.
