Notice also that you have to decide whether you want to communicate
over a pipe, or directly inside TeXmacs (which assumes that you
use Guile Scheme and not PLT scheme).

That is certainly what I had in mind.

We already do provide some "flattening facilities" (see the other
plug-ins and Help -> Interfacing -> Mathematical and customized output).
A student is also working on an integrated parser/pretty-printing tool
written in Scheme. If you have some free time, then you might be
interested in helping him.

Carefully read the whole section Help -> Interfacing. Two third of it
is bound to be interesting for you. You may send TeXmacs trees using
the "scheme" format. I also recommend you to take a look what other
plug-ins do.
