Correct: they do not require tables.

Yes.

Sorry, but I cannot understand the question.

I never said any such thing. Scripts are independent of language, but 
scipt usage can be language-dependent.

It is not so.

MIME body part headers allow MIME language tagging; mail subject 
lines do not allow MIME language tagging, but do allow Unicode 3.1 
language tagging. Neither has had much success in implementation, and 
inconsistent use causes poor display.

No, they don't. MIME body part headers cover the entire message, not 
individual characters. Unicode 3.1 language tagging is applied to 
groups of characters, but so far, there have been no common 
implementations. This is probably because it is tedious for a user to 
have to insert tags into simple text saying "these characters are 
from this language, but these other characters are from this other 
language".

Because that is not how the DNS works. What you propose makes perfect 
sense for a directory system, and is being actively pursued in many 
places. In fact, this one of the reasons that people want to abandon 
using the DNS for naming things like companies: it does a very poor 
job of it. The IDN WG work will make that poor job a little better 
(by allowing more characters), but it will still be fairly poor.

One record would be all-traditional, one would be all-simplified.

I hope I have answered them all!
