Default is to power Wisp628 from the target. Some extra circuitry is
needed for chips that configure thier /MCLR as input, because in that
case the programmer must briefly remove (short!) the power, while still
running itself.

I don't know. Does a PP have Python? (It probably will if it has a
decent (= 32 bit) C compiler). Does the Python have access to the serial
port?

Actually I have been thinking about two options:
- use a PIC that can self-program, but those are more expensive than the
F628 used now
- (for a future USB version) upgrade via the bit-bang mode of the FT
chip (using LVP).
But neither will apply to the current Wisp628...
