I am shocked and apalled that people even think about mating emacs with OO. Blasphemy!!

I am also surprised that nobody remembers Texmacs. Texmacs is great and what emacs should've been "out of the box" years ago. I believe it uses some sort of a stripped-down 
TeX system - the whole texmacs package is  about 20mb, and is _standalone_.

Also, mating emacs with    OO will    add fragmentation to community - people will be forking their own emacsen    cause they want
to keep    it lean    and mean.

cheers!
