Absolutely!

Well how would we send it out? If we send it just as
a string of text how will we pass the start and end
positions of squiggles?
If we pass it in internal format it'll be yucky for
grammar types to hack on. We'll also have to watch
out for inline level attributes such as bold and
italic
which we don't want to bother the grammar checker
with.

Yes let's do it as OO as possible.
