currently yes, but in the future it may become an option.

probably having the client include its preference would be better than to 
have them statically configured, but having a static default in case the 
client doesn't mention its preference is desirable as well.

that you know when the request/reply ends.
I guess I addresses them too broadly by saying "all transports", but I was 
only referring to the openser internally developed protocols that are 
line oriented.
