Not so much lame, as awesome :)
Yes, there will be a little more work required than what is done in
the RSFAjaxAHAH sample that Aaron put together, but this is the basic
workflow that we want. Stripping out the head/body material with a
bunch of regexps and re-injecting them into the global <head> in a
traceable way is what we are after - this has also been demonstrated
in outline to be possible (the injection part) in the Camtools
Widgets set and just needs to be orchestrated a bit.
In terms of "require all things that want to be rendered this way to
follow some rules" is exactly the set of guidelines that we are trying
as well as being multiple-include resistant and if possible version
tagged, as well as portal-safe in all the usual ways. We are fortunate
in that we are starting from a "safe baseline" - all the things that
we might seek to aggregate in this way are either
i) EntityBroker worlds (which are almost all currently written in RSF
and hence follow some basic rules on markup, URL semantics etc.)
ii) Camtools-style widgets, which follow a naming layout that
also guarantees some basic safety (namespacing has been being followed
and afaik all use a fixed version of JQuery etc.).
So we will not be struggling here to impose order on a bunch of
random junk (e.g. JSF tool output) that could never be kicked into
some kind of shape. Fluid is actively working on ensuring we can both
find ways of expressing the rules that things should follow, and also
providing a framework for following them easily - for example here is the
page explaining strategies for versioning
and here is the JIRA where multiple version resistance will be tracked
for inclusion in the next 0.5 release for Fluid:
which is a required deliverable for portalised environments like uPortal
in any case.

Yes, I agree that perhaps in the very short term, we might want to just
put together a popup-based approach - either in tabs, or else perhaps
in a dialog/thickbox style using perhaps (gasp!) a temporary frame.
For things like message centre, this will probably be all we can ever
do with it... until it becomes either Entitised or JSONified (possibly
