[Orgmode] Collaborate with heretics

[andrea]

In university projects I use org-mode for writing assignments and
everything else I need to.

Given that the output is wonderful and it's just text my group mates
were very happy or at least didn't offer another alternative.

But the problem is that those people are not emacs users.
One actually is but he still didn't get the beauty of org-mode.

Anyway in this way they insert text and then I have to fix all the
indentation/style errors that are normally done by people not using it.

So the question is, is there another way to edit org-file not from
inside emacs?

Just simple editing (struct-mode and table-mode) would be more than
enough, it doesn't need to have all the power it has normally....
