As i said, this has to be hacked before using it... but... hummm.. it will only need +5V, GND, PGD, PGC, VDD signals... the same as PICKIT2 will provide.

It doesn't worth to invest for PICFlash programmer.

Real ICSP is more valuable... unless you want to program your PIC... then ship them without any PCB. Who want to ship something without testing it? well... not me Hence why the ICSP is handy... at very least for me.
