Matthias,

don't know if this helps, but we do this in Qpid, and it works quite well. Also
in AMQP 0-10 and AMQP 1-0 draft, you have message credit which is the what is missing
on 0-8/0-9 to be able to implement this - thus the producer can be flow controlled. Complex 
policies can be implemented using this mechanism. The simplest that we have implemented in 
Qpid is to be able to specify a max publish rate for example for a producer.

maybe that gives you some ideas as you move toward 1-0
regards,
Carl.
