Hi Marc, for messages of that size, I'd definitely recommend using FTP. You can find examples of how to use FTP with blob messages in this test case
http://fisheye6.atlassian.com/browse/activemq/trunk/activemq-core/src/test/java/org/apache/activemq/blob/FTPBlobTest.java?r=HEAD (and some more in that package). Of course, tests are using embedded FTP server, but you might opt for an external one.
