There have already been relatively simple ways of unprotecting a PIC. 
Bunnie (the guy who hacked the xbox) did it with the 18F1320.

Read up. Interesting way microchip protected the CP bits, and 
interesting workaround! (for those who don't want to read up: the config 
word bit cells have metal shields on top of them to prevent selective UV 
erasure.  But if you angle the chip the light seeps underneath.)
