   Two thoughts:
1) Seems like we also need a 'port broker'. Isn't that function served
   by PIPE:, or am i missing something fundamental? I.e. rather than
   use ports, just use PIPE: which strikes me as being more reliable?
   Or do we lose something valuable by not using ports?
2) As for the message broker, make it a library, then we in effect
   have multiple copies running for each client ( i am thinking
   as opposed to having a 'port manager' task which will be 
   a bottleneck)
