Yeah, and although C does not make XML-RPC that easier (as it does not
make anything easy...), there are plenty of libraries to help
interfacing from C/C++, with more high level languages being
transparent to make that access, so one could interact with Emacs
using Lisp, or Python/Ruby for plugins in most editors... or Java
inside Eclipse and other IDEs.

The point of this support is to remote control Editje and also get
informed of some resources. For instance, list all the groups, or all
the parts in a group. Get notified when them are added, modified or
removed... Know when people flag the "api:" attribute of parts or
scripts and that way we could present TAB-completion in such editors,
or just show a tree-view of the groups for easy lookup by users
(avoiding grep or extensive searches in the .edc).
