Cheating bypass

I am developing a plone4 site where every user has a sortable inventory of items. The ATFolder folder_content view is ideal for this. The only problem is that instead of the url:

/site/user/inventory

or

/site/inventory/user

URL should be:

/site/inventory

I thought of several solutions, but each has its own doubts.

• Make inventory contents dynamic, depending on the authenticated user. I don’t even know if this is possible on plone.
• Somehow fool the transversal mechanism, so / site / inventory render / site / inventory / user.
• Change the context before rendering the view. Again, I do not know if this is possible.
• ATCTContent, . , .

?
