Here is why I don't like n3680.
ISO-3166-1 defines two-letter symbols for many "pieces of earth" which
are not independent countries.
For example, there's an ISO-3166-1 symbol for Réunion, an overseas
department of France.
Why would Unicode define a flag for Réunion (RE, also known as FR-RE in
ISO-3166-2) but not for Puy-de-Dôme (FR-63, a metropolitan department)
or Bretagne (Brittany, FR-E, a metropolitan region which has its own
flag:
http://upload.wikimedia.org/wikipedia/commons/7/7d/Flag_of_Brittany.svg)?
If those flags are used for languages, Brittany has its own language:
Breton (Brezhoneg). So, a support for ISO-3166-2 could be a good Idea.
Also, the flag of Québec (CA-QC,
http://upload.wikimedia.org/wikipedia/commons/5/5f/Flag_of_Quebec.svg)
could be used to make a difference between European and Canadian French.
Unicode is supposed to be a stable standard: any new character will
remain always and forever.
ISO-3166 is not stable enough to be encoded as it is in Unicode:
countries may change their names, countries may merge together,
countried may be divided into several parts.
In any case, new two-letter codes may be created, existing ones may
become obsolete and, most problematic, when a two-letter code has been
obsolete for at least 5 years, IT MAY BE USED FOR ANOTHER COUNTRY.
For these reasons, I think the system proposed by Philippe Verdy would
be better suited to encode flags: the codes would have no meaning by
themselves, but their combinations would be displayed as flags, whenever
possible, by the rendering engine.

In the following lines, I'll use abbreviations.
For example,
FSIA = FLAG SYMBOL INITIAL A,
FSMHY = FLAG SYMBOL MEDIAL HYPHEN,
FSF9 = FLAG SYMBOL FINAL 9.
When used alone,
FSIA would look like
??
?A
??
FSMA would look like
?
A
?
FSFA would look like
??
A?
??
And FSIA FSMA FSFA would look like
?????
?AAA?
?????
if there's no rendering engine able to convert it into a real flag.
So, the flag of the United States
(http://upload.wikimedia.org/wikipedia/commons/e/e2/Flag_of_the_United_States_%28Pantone%29.svg)
would be "spelled"
FSIU FSFS
It would look like
????
?US?
????
The flag of Nunavut
(http://upload.wikimedia.org/wikipedia/commons/9/90/Flag_of_Nunavut.svg)
would be "spelled"
FSIC FSMA FSMHY FSMN FSFU
It would look like
???????
?CA-NU?
???????
The flag of Chiriquí
(http://upload.wikimedia.org/wikipedia/commons/3/3b/Bandera_de_Chiriqui_%28Panam%C3%A0%29.svg)
would be "spelled"
FSIP FSMA FSMHY FSF4
It would look like
??????
?PA-4?
??????
Etc.
I first thought we could get rid of the hyphen because all the country
symbols are two letters long, but there are four letters long country
codes in ISO-3166-3, therefore removing the hyphen could lead to some
conflicts.
