In regards to the bootloader, if I built the larger board with a bootloader I would not need a programmer onboard. I would need one to do the initial programming with a new chip (or after a smoke-out) but I could use my K8048 as the programmer only when necessary.
But then again, a built-in programmer would only take up a few square cm.

Well, this is 1 if I understand bootloading.......Does bootloading work with ICSP?
