Anyone know if this exists? I'm using a 16F876.

But all the bootloaders I've found say they don't work with the protection bit set. Anyone know of a bootloader that works with the protection bit?

I thought it was pretty much what I wanted, but then I noticed it was for the 18F series. Almost! I'm using the 16F8XX series. Know of any for that series?
