Acquisition isn't available in __setattr__ :(

CMFCalendar.browser.event (on SVN trunk) does something similar, but in 
that case an adapter is used. The wrapped object is the context of the 
adapter, not the adapter itself. So the aq_chain is not destroyed in 
__setattr__.

No idea. (Besides using an adapter.) The 'tools as local utilities' work 
currently done on CMF trunk will make this much easier. You no longer 
need Acquisition to get the tool (=utility).
