I am not sure if that has been a deliberate decision but apart from 
naming it has not really been that visible so far.

I think what happened was the Remoting test suite had tests that had 
local and remote connection providers registered and then these names 
have stuck as new communication libraries have followed the test suite.

So those names work when using the remoting APIs directly but are not so 
good once you are using an alternative API that is wrapping Remoting.

I think whatever set of protocol names we choose they are going to need 
to be ones we can live with long term.  The suggestions for Remoting JMX 
I think are fine, if we ever wanted pure http for JMX that could be a 
new library with a completely different protocol in the Service URL.

However another question for 'ModelControllerClient' are we also sure we 
will never want to add support for pure HTTP invocations?
