He still did last time we talked about it, which wasn't too many months
ago.  Although some of the potential legal nastiness, particular if it's
done deliberately as a frame rather than just exploiting the open

he's in the position of being a more likely potential target for such
things than most of us.)

don't get it right, so there's *support* work too. So my party network is

Maybe I should load it onto a thumb drive to pass around; though that
wouldn't help people like me that might want it on a smartphone or tablet
