Pages can use different dictionaries/languages in the same document.
So this is perfectly possible with OS X to do such a thing.
The Pages user is expected to add a language attribute to any part of 
the text.
This language attribute is stored in the file.


Doing such a thing is not possible with mail, because the mail file 
format does not authorize it.
It is not a limitation of Mac OS X, but a limitation on the mail system.

For the particular case of LaTeX, the language is somehow encoded in 
the file.
So it is in theory possible to have the spell checker switch to the 
appropriate dictionary while parsing the file.
 From the developer point of view, there are 2 problems. The first one 
is to find the appropriate dictionary,
the second one is to ask the spell checker to use it properly.
This last point is rather easy.
The former needs a parsing of the LaTeX document and this operation is 
extremely time consuming, much more than syntax coloring especially 
when the language switches are spread between different documents. 
Pages uses XML, and language parsing has no supplemental cost.

One viable solution is to use a simple rule: one file one language and 
split the document accordingly.
This is how iTeXMac2 behaves. One advantage is that it is not tied to 
LaTeX. But this is actually not comfortable if the document contains 
many language switches. It would be more comfortable if included 
documents were viewed inside the container (something like auctex does 
with graphics docs)

It seems evident that one cannot guess for sure the language from a 
single word, just because some languages are so close from each other.

So Mac OS X is able to deal with different languages in the same 
document, but it is very hard when sticking to LaTeX.
