Ispell/Aspell are, to my knowledge, the only spell-checkers providing
the piping mechanism Emacs uses - Hunspell has a C(++) interface only.
Currently, all we do is send some buffer text to the spell-checker and
wait what the spell-checker tells us about that text.

IIRC integrating spell-checking wasn't that trivial with Open Office and
Thunderbird either - especially when using some European languages like
German.

Grammar checking can (and should, IMHO) be done separately from
spell-checking.  Neither Aspell nor Ispell provide any support for this.

That's what I do with speck, I send one line of text to the
spell-checker at a time.  I don't want to send more since this might
interfere with typing.

Currently, Aspell and Ispell know better what should be ignored in LaTeX
buffers.  Why duplicate work in this area?

I'm not aware of such an API.
