Suggestions about separation and ISO code

There is no shortage of codes for countries. In my programming, I usually use the 3-letter codes of the International Olympic Committee, since what I write is generally sports-related.  But for this purpose, being able to match codes with the CLDR is the most important criterion (other than backward compatibility), and that argues for ISO 2-letter.

Internet top level domain names for countries are 2-letter codes, derived from the ISO list. More people know something about the internet country codes than about 3-letter ISO codes.
More or less related are the US Federal Information Processing Standard
(FIPS) 10-4 codes, also 2-letter codes.
