The nsIJRILiveConnectPlugin interface defines additional entry points that a
 plugin developer needs to implement in order for the plugin to support 
 JRI-based LiveConnect, as opposed to the standard JNI-based LiveConnect
 (which new in 5.0).

 Plugin developers requiring this capability should implement this interface
 in addition to the basic nsIPlugin interface.
