this can be done but using non-destructive consumers. The messages can 
then be discarded via a
variety of mechnism. Using the C++ broker the following options exist.
- Using TTL to age and destroy the messages.
- Size limiting the queue for discarding old messages via a size policy 
like ring.
- etc
On the Java broker,
TTL would be the way to go.

And ten of cause you can create an autodelete queue for each consumer. 
not really any cost
in doing this also, allow destructive consumers.
