[Radiant] Google sitemap.xml support + ActionView helpers in behaviors?

[Xavier]

Hi folks,

I added a tiny extra chunk of code in my SiteController to generate a
sitemap.xml file (
http://www.google.com/support/webmasters/bin/topic.py?topic=8467 )
from the list of all published pages.

If there's any wider interest for such a feature, I could package it
as a Behavior.

Is there any way (or plan) to inject default ActionView helper method
(such as link_to, ...) to Radiant behaviors?  I doubt a simple mix-in
would do the trick but I admit I haven't looked at it yet.  Wouldn't
that be terrific if behaviors had access to all Rails bells and
whistles?  Especially when some custom Radius tags generate more
complex output...

Cheers,

Xavier
