I know there are about a gazillion different ways of making serial 
numbers, but what we have is a two-octet (uint16_t) number at a 
predefined location in the eeprom.

So, there should be a box into which the serial number is fed, and then 
the eeprom content is changed accordingly before programming the chip.

If I look at other programming software, the things that seem to be 
there most often are:

- format of the number:
  - binary 2 octets
  - binary 4 octets
  - ASCII at some length with or without null-termination

- location of the number
  - either flash or eeprom
  - position


Then--depending on which way the production runs--some users might wish 
for an auto-incrementing function. The counter should advance by one 
after each successful programming. (In our production we glue some 
stickers onto the PCBs before they are programmed, and the serial 
numbers are given according to these stickers, and thus we do not need 
the auto-increment.)

I really cannot imagine all possible needs, but I think that if the 
following options are available, almost everybody should be relatively 
happy:

- starting position and memory
- 2-octet binary, 4-octet binary, arbitrary length ASCII (padded with 
NULLs to the given length)
- auto-increment

I do not think this would be very difficult GUI-wise, just a single text 
box for the S/N, and then rest of the settings in the menu.
