I understand what those are like. I work with a club that sells
electronics kits (www.njqrp.org) and we ship them all over the
world and it does sometimes become an issue. But, for something
like this, if you put 'gift' or 'sample' it generally passes
right through.

I see the distinction.

I like your solution, too. I'd be very curious to see it working.

Right, we just want *one* chip programmed and then well go back to our regular
tasks.

Fully.

Certainly. Both are valid ways to get a chip programmed. :) They
both have things to recommend them and drawbacks, as well.
I'm looking forward to having to dig out a 555 so that I can try
your bootstrap programmer scheme. It looks fun!
Cheers,
