It's using PicForth's own serial monitor, slightly patched to accomodate 
the needs of the A chips (while still ok with pic16f873x). (Patched 
version is included in kit).

Which means that on the PIC, it's all PicForth - no third party software. :)

The PicForth serial monitor weighs in at around 460 bytes, bigger than 
the average bootloader, but does have a command interface for 
reading/writing prog memory, data eeprom and RAM - good for looking 
inside the PIC via minicom (or any prog talking to serial port) without 
needing to move the PIC to the burner and rip the image.

Since the serial monitor has commands for writing to program memory and 
data eeprom, plus setting boot vector, it works just fine as a bootloader.

The client program (pfd.py) within the kit just issues the appropriate 
commands to the serial monitor to write the program image to PIC program 
memory.

You'd have to extensively hack the client utility to support WLoader's 
different protocol, or (probably better), write or find a whole new client.

I believe in always trying to give back when I receive something of benefit.
