I thought prestige was proportional to the weight of the "kit"?  The
really good guys get more than one laptop (one running "standard
windows", the other running linux, or macos, or something else.)

In any case, it looks to me like the picKit2 would be a fine
starting place.  According to the schematic, there's an ICSP
connector on it somewhere (for the onboard chip, not for the
device being programmed.)  Tie into that and you can provide
both power and a couple IO pins useful for accessing a display
and SD card (three pins should be sufficient for bidirectional
timing-free communication, eh?)  Assuming you don't just use
the existing 1Mbit (NOT 1Mbyte, right?) of eeprom...

And the general design looks clone-able if you want nice
packaging.  Use the microchip code for its programming algorithms
and add you own UI around it.

Or maybe you should have a device that connects to a cellphone?
