Thanks Bert, that clears it up. I will check the GUI and see how they handle the data, and try to see if I can figure out what would need to be changed, if this data array is made small enough for PBP to handle easily.

I know this is for 16F, but if we made the buffer about 50 bytes, it could be made to bootload to a 8 pin 12F1822, which would be pretty cute. I don't think it would take too much longer to program, as it would just need a quick checksum and response from the PC.
