By proto in this case I was thinking of say an alternative transport 
like sctp or infiniband or suchlike e.g.


I'm *mostly* just thinking along the lines of how one could make this 
part of the address the same as say Proton Messenger as I think that the 
closer qpid::messaging and Proton Messenger Addresses look 
(notwithstanding differences borne out by one being connection oriented 
and the other message oriented) then ultimately the less confusing it's 
likely to be for users.

There's clearly also the Java ConnectinURL to consider too, but again 
from my perspective I'd quite like the maximum amount of cohesion - I'm 
a bit simple minded and easy to confuse :-D

when you say the same scheme do you mean that the python client uses 

Fair enough comment. TBH I mainly mentioned it because when I was going 
through my exercise of trying out various AMQP 1.0 subscribers I was 
starting to find the:

--connection-options {protocol:amqp1.0}

A little bit less aesthetically pleasing than the sort of


Addresses I was using with Messenger, so I was idly wondering if there 
was a way to specify addresses of the same form on qpid::messaging so I 
could avoid needing explicit connection options for being AMQP 1.0 and 
the user/password stuff

If the amqp:// prefix isn't unambiguously 1.0 then I take your point, I 
had assumed that the URL was either <host>:<port> or amqp:<host>:<port>

in which case amqp:// would have been different.
