I would call the second parameter 'sync' I think, it would be a boolean 
which when true would give the current synchronous behaviour, i.e. the 
call would block until the server responded (and would then throw an 
error if the server indicated there was no such node or its properties 
were not as requested, or permission was denied etc). If the value was 
false then the call would return as soon as the request had been issued 
and return from the method would not guarantee that the sender/receiver 
was actually linked to a valid node.
