I have implemented everything except the getServices().  It is about as
performant as it is going to get.  All of the data structures needed for
the root model are kept by the MenuContentHandlerImpl (and thus, the
root model which contains the entire tree, is shared). Upon each
request, the root model gets rebuilt, but that is trivial, since it just
goes to the MenuContentHandlerImpl to get its TreeModel and hashMaps
(which are already built) -- so no parsing is done, no going through the
tree to construct the hashMaps is done.

Sounds perfectly reasonable to me.

My question to you Adam is when is the ClassLoaderUtils going to be in
incubator?  and what will be its package?  I can't seem to find any
javadocs for it, do you know where they are?

It's already there;  look in:

http://svn.apache.org/repos/asf/incubator/adffaces/trunk/adf-faces/adf-faces-api/src/main/java/org/apache/myfaces/adf/util/

I've realized that XMLMenuModel is necessarily a per-request object;  it cannot be 
shared among multiple users or threads (the iteration through model makes the 
object stateful and single-threaded).
