In principle this is true, but I think RefTeX is deeply intertwined with
the assumption that it is running in a LaTeX buffer.  Going through its
code and making it major-mode-agnostic is a worthy project all of its
own.  But it might take less effort and be more long-run maintainable to
just wire up the bibtex.el bundled with emacs, CompletionUI
(http://www.emacswiki.org/CompletionUI) and YAsnippet
(http://emacswiki.org/emacs/Yasnippet).

One could do this with font-lock and the new citation syntax I proposed
in my other email.  We would need two alists.  One would pair citation
lookup types with functions to resolve them to a location, and to get
their properties.  The other would pair display types with two
functions: one to return a format string that would be displayed by
font-lock instead of the citation markup, and one to return the code to
export the citation.

So, a citation like [cite:doi:parens:some-doi:key=val&key2=val2] would be
displayed by:
1. call (org-lookup-cite-doi "some-doi") -> (:author "Foo" :title "bar" ...)
2. call (org-display-cite-parens '(:author "Foo" :title "bar" ...)) ->
   "(Foo 2000)"
3. (font-lock puts an overlay over the citation markup, with the
   returned string)

If you click on the citation, org would open the location (URL or local
file) returned by (org-resolve-cite-doi "some-doi")

A citation could exported by calling (org-export-cite-parens 'doi
"some-doi" (:author "foo" :title "bar") current-backend).  This function
could just return \parencite{foo} if exporting to latex and the citation
was already in a bibtex file.  But it could also just return “Foo 2000”
as a static string for dumb backends like ASCII, or write the
information to a temporary bibtex file (so that latex can atomatically
use the bibliographic info looked up from a DOI citation).

In any event, this is a big, complicated project.  Step zero for me (and
many people, I guess) is to get a slightly less hackish way to export
Bibtex-based citations to latex, and the other pieces can be built on
top of that.
