and one of those standard interfaces, as was mentioned before, is
Bonobo::Application, which I just had a look at. And really, it seems
very well suited for scripting. An app just has to implement that
interface, which is:

		any         message      (in string  msg,
                                          in ArgList args);
                long        newInstance  (in argv_t argv);
                MessageList listMessages ();
                string      getName      ();

so, you can get the list of messages an app accepts very easily from a
client, and then call those messages. The MessageList type contains all
info for every message, such as its name, the argument types, return
type, a description. So, you can even do a GUI frontend to quickly write
scripts and do code completion on the message calling.

So, an app will just have to define the set of messages it will
implement, like OpenNewDocument, SaveCurrentDocument, etc, and clients
can just call those messages.

It looks quite straightforward to me.
