I guess you can do it by creating a custom node type with a mandatory 
property that stores the last update timestamp. WDYT?
the first line of your example would be something like:
Property p = (Property) 

But since graffito, lenya and jackrabbit communities are interested in 
such a tool it would be cool to work together, that would be the apache 
way, right? :). AFAIK the proposal discussed in the graffito dev list 
deals with many of the issues you are talking but I didn't see any 
reference to a cache with already mapped objects.
