Metal Storm are part of the dynamic demonstration which is very encouraging however the part that I like most is this

NON-LETHAL CAPABILITIES ON EXHIBITION AT 2011 NATD

To confirm and demonstrate existing, or soon to be fielded (Technical Readiness Levels 7 to 9), non-lethal technologies with a view to facilitating the rapid
fielding of non-lethal capabilities in support of the NATO mission in Afghanistan


So one would assume from this Metal Storm has Non Lethal
weapons at TRL 7 to 9 levels...nice to know..
