Wow, you are really terrific (fantastic).
My friend had a design which took him one year and he was making a lot of money out of it. There were also competitors making similar product, in Singapore, like his but was more complicated and cost more to make. And after selling his product for about 2 years, his circuit was cloned and improved (in appearance) in China by his competitors and he lost his business. He was wondering how his PIC was cracked though he already burnt the code protection bit during programming. Luckily he still has other products which no one want to clone!
I'll send you a personal email to discuss about the ICD firmware OK?
And thank you for sharing your precious experience here.
