Hi Felix,
How about having a per-framework URL Handler registry just like the URLHandlers class which is registered as a service. This service could serve URLs and content handlers by calling the system URL factory first (after checking for the "bundle:" protocol) and then the locally registered handlers.
Felix already does provide something like that. Have a look at: http://svn.apache.org/viewvc/incubator/felix/trunk/framework/src/main/java/org/apache/felix/framework/URLHandlers.java?view=markup
