Ok, that makes sense.

Remoting has no state, or direct awareness of transactions.  However, whatever service you're connecting to by way of Remoting may (and probably does).  The reason Remoting 3 has this capability is so that there's a single standard way to propagate transaction state between endpoints - whether it's a database to an app server, two app servers together, or two client applications that don't even know anything about JTA or JCA or anything like that.
