Thanks for your interest in Rave. We are always looking for new ways to
utilize the Rave platform and hope you can share your work with the
community as you go.

It is very easy to include custom code in the container (page). All you
really need to do is customize the custom_js.tag file and point to your
custom javascript. This will allow access to that script from the page. As
for injecting code into the widget, I'm not sure the best way to do that
with Wookie. With OpenSocial gadgets, you could have a custom feature and
reference it from your gadgets.

As a general note, Rave already supports OpenAjaxHub for IWC. Again, I'm
not horribly familiar with the W3C widgets (Wookie) but on the OpenSocial
side all you have to do is include the pubsub2 feature in your gadgets and
pub/sub works like a champ. I suspect you can already do it from the Wookie
side as well but someone else will have to confirm.
