I've put together a crude mechanism for starting/stopping routes by the name
of their endpoint.  I do agree however that adding/deleting is probably a
nicer way of dealing with state.

I had to patch two classes in the Camel library. 
The EventdrivenConsumerRoute has to retain its consumer so that addServices
(and hence ServicesForRoute) always returns the same answer. I need this to
actually get at the registered consumer for a route. 
This patch may affect other portions of Camel that I am not yet aware of.

The second one is related to state management within the ServiceSupport
class. Here in the start method the states stopping and stopped are now
explicitly set to false. IMO this reflects the intention more clearly
anyway.

Finding routes by name boils down to crude lookup. 
>From the context you can easily extract both a Map name -> uri and a map
uri->route. Together they give
you a mapping name -> route. I don't think there is an easier way right now.

It was a long shot but shutting down a JmsEndpoint nicely shuts down all the
processing (or so it seems). Restarting an endpoint required patching the
ServiceSupport class. 

I've attached the code right here.
