[Zope3-dev] traversing path from scratch

ok, folks: I have a physical path stored from a traverser
self.subscriber_path=getAdapter(
subscriber, ITraverser).getPhysicalPath()
later on, from another method in this object I want to use the stored path to
get the original object. If my object were wrapped, this would be easy:
return getAdapter(self, ITraverser).traverse(self.subscriber_path)
However, I have nothing wrapped available to me at all. In effect, I want to
do
return getAdapter(None, ITraverser).traverse(self.subscriber_path)
However, the default Traverser implementation (Zope.App.Traversing.Traverser)
needs to have a wrapped object to work with to get the root folder.
Any ideas? If I could get a wrapped root object I guess that would be good
enough--can we have a global component that returns a wrapped root folder for
situations like this? Is there a reliable way of getting the root folder?
Should this be turned into a component, if so? Because of the importance of
this, I'd be tempted to make it a global service myself, i.e.
getService(None, 'RootService').getRoot() except that looks kinda stupid and
I can't think of what else we would use such a service for...
Help?
Thanks
