That same problem exists for mime-type handling and has been solved. We 
can do something similar. If MC can not resolve the request to a unique 
handler, either it picks up the one which has been set as 'default' 
(somehow) or picks up anyone of them (it doesn't matter because all of 
them are equally capable of handling the request).

I think you still hit the problem with that approach. The managing 
entity would need to figure it out.

At least for protocol specific overrides, it can work (.chandler just 
needs to mention specific protocols that MC should prioritize the 
handler for). For prioritizing within the same protocol, I don't know. I 
don't see the point either.

Thanks.
