If each Cassandra instance will be on separate a node you should have no problem embedding cassandra inside another java process. With JBoss and Cassandra both using JMX, there might be a few things to trip over, but nothing insurmountable. If you want to run multiple embedded Cassandra instances on a single host (inside of a single parent java process or several), you are in for a fun ride. (Multiple Cassandras in a single process isn't possible yet.) Gary.
