Could you explain a little more about your use case - it sounds
interesting :). Do you only want to fetch a single message with a
different filter per message, or just change the fliter from time to
time. If its the latter then creating JMS consumers is pretty cheap &
you can use any JMS to do that. Though the former, there's no 'give me
a message using filter X' type operation.

FWIW it wouldn't be too hard to add this to blaze or activemq - its
just a different kind of operation. Messaging systems are usually
designed for asynchronous streaming of messages, so you subscribe and
receive many messages etc.
