The first is probably not possible. I think that this is not too difficult
in Emacs because there is already code to do version control. The third is
also difficult, simply because an editor is created for a particular R
process. Copy and paste would work, though :-).

Could you explain the second item (literate data analysis/programming)? I
have a vague understanding of literate programming (mostly in the context
of Web), but I don't know very much about it.

The fourth item might actually be possible in the next major version of
GTK+ (the widget set that Gnome uses). However, that's a little way off.

Based on this, I'd say that it will be pretty difficult to replicate ESS's
functionality. I guess some people will be sticking with Emacs (strange
people... ;-).

Very cool idea. I'll have a think about how to do it (finding the time
to actually implement it is another matter).
