[Gluster-devel] number of connections

There is just one connection between a client and server.

the client only 'connects' to the specified 'option remote-subvolume'
in the client/protocol section. other volumes are implicitly used
depending on how you have constructed the graph on the server side.

It might be intersting to write an 'arbitrator' translator which
arbitrarily assigns calls to one of its N children in some
ordered/random fasion. Each of the children can be a seperate
client/protocol transltor configured to use different IP, hence
differnt interface, but in the end all of them connect to the same
glusterfsd.
