Aditya,

Since your actions can map URL's in different ways, it
may not be easy to dynamically create a sitemap object
in the way you are talking about.  Because if an
action accepts parameters than it can potentially map
to a large number of URLs.

If you just want to have some additional information
placed into the stash for all the actions in a given
controller, you can do that in a :begin action, which
is run for each request to a controller.

However if this information is presentation related
you might prefer to place it into a configuration file
for your view templates.  For example if you are using
Template Toolkit, you can include a template that just
defines some local information.  That way you can
modify the information without having to deal with the
controllers.

Not sure if I am helping.  Good luck!
