I've seem some discussions on bootloaders and
something about a device that would simply allow a
field upgrade to an existing device...I think.

Seems to me, that you could stream out the hex file
with a device, that provided the Vpp to actually do a
field update.  Simply send it out to the customer,
they reload and send the unit back.

I'm sure they exist....I'd like to see one for an
16F877, but again, its the programming algorithim that
changes from chip to chip.
