Did you know if exists some example stack around, to perform and answer to
an UDP request?

I thought that $USER should be valid because: 1) a license is valid, in
effect, only for one user (think about a corporate with hundred of stations
that buy a copy of your app). 2) For a single user with 2 computers, in most
of the cases he will have the same account user name on both, and you can
also add a button in your site to automatically furnish a new code to a
registered user. I don't think to invest very much in protection, but a
simple - universal - license code, will put too easily your app in the
pirates market.
