Not sure what the "alwaysRemote" bit is for. The other code is there
because the old domain manager was able to decide if an endpoint was
referenced remotely and set an absolute URI in that case.

If we want to run off the endpoint registry alone we don't know
whether a endpoint will be used remotely before we come to start it.
So in that configuration we probably need to enable a remote endpoint
if the interface is remotable for the time being.

A future solution could be to only start sca binding endpoints when a
reference is registered that uses it.

+1 and we need to find a way to pass in the default binding
information for a node rather than relying on the domain.

Right, this is the point about passing default binding information
into the binding URI calculation. Can we have a node configuration
file for this kind of info. I'm not suggesting that we use a composite
file as we do currently in the 1.x domain manager. but a specific XML
file for configuring the node. Could contain.

node configuration info (if not provided on command line)
default binding information
pointer to (or nested) composite file to describe management services
that node provides (future feature)
