I love it! I'll host the programming software on the web site and now we
have total port independence.

Remember when Byte Magazine was printing software in barcode? Same thing,
but with a pair of phototransistors focused on the paper. Now you can fax
your updates to the remote office.

There should be a contest: "Most unusual interface to program a PIC that
actually works."
