It seems like myghty resolver does this as well...you send in a URI,  
and as it walks down the chain, it can hit FileResolver (returns file- 
based templates), ModuleResolver (returns python callables), each of  
which are free to return whatever Component object they want if they  
have something to offer for that URI; each Component just has a run()  
method.   you can inject whatever customized rule you want to return  
something else at some point.  rules could be constructed to return  
an adapted version of any other template's template object too.
