OK.

This and other 'time based' behaviours are frequently requested, but
*alas* are not yet built-in to RabbitMQ.

However, don't give up.  You could create a consumer (in any language)
which managed this for you, eg enforcing a disconnect after some time
has passed.  Or, if you are feeling brave you could create a plugin to
do this 'inside the broker'.  Plugins have to be written in erlang.

I hope that helps.  Perhaps the list will have more immediately useful
suggestions.

Cheers,
