this is great! We miss though, if you are going to use d-bus, a good
query mechanism, so that we can query all the installed actions without
having to start individual applications.

as you said in the document you posted before, the UI can be dinamically
generated from the description of the methods returned by each
individual application. That should work pretty well for simple types,
but not so well for other types. So I would suggest there is additional
information on each argument, like the allowed range, the set of valid
values, if it's a file, what kind of file it is (if it's an image, for
instance, show a preview, etc), ...
That would solve the UI problem, since building the UI automatically for
any desktop/toolkit would be quite easy.
all this sounds really good, and something I have been wanting for long
(the scriptability stuff specially), so, when are you releasing it? :)
No, seriously, is there any code written yet? where is it?
