OK, I see. It has just occurred to me that you were using the Java
client to accomplish this task. Just FTR I wanted to point out the
existence of the Ruby (http://github.com/tmm1/amqp/tree/master) and
Python (http://barryp.org/software/py-amqplib/) clients which are
slightly more amenable to scripting that the Java library is.

No that seems reasonable from the perspective that a catch all binding
key is simpler to maintain that requiring knowledge of the entirety of
all possible routing keys.
