I have a heavily modified version of a YAPP (not YAP) programmer
that downloads via a true RS-232 connection.  I have source
for the firmware and the programmer software which I have
modified form the original.  The design uses a 16C54 or 16F84
to do the comms and the burning.  I modified it to burn
16F877's.

I suppose that someone could start with the same programmer,
add a serial EEPROM to store the binary image downloaded by
the PC and burn as many PICs as you wish from the downloaded
image.  It would sure as heck save time download time over
the serial port on subsequent burns.  A 32K or larger serial
EEPROM could store several images to select from for
different devices.  Add some LEDs to indicate pass/pail, and
some kind of display to indicate which device and image
are selected.

I have no use for such a thing, but it would seem like an
interesting project.  I'd rather spend my time working on
my robot projects.  I only burn 'em one at a time any way.

I got it from http://www.picpoint.com

Look for YAPP!  the web site was under construction last time
I looked so you may not be able to get to the archive.  If
you cannot find the project anywhere here is the author:
