OT: Technology alert - guns that fire 1,000,000 rounds per minute

Metal Storm is back in the news with a 15 barrel weapon that fires at
rates of 1,000,000 rounds per minute.  One blurb says that rates up to
13 million per minute are possible.

Video footage can be found at the web site: http://www.metalstorm.com
under the Technology Demonstration page.

Other forms of the technology have been demonstrated to fire 40mm
grenades at a rate of 20,000 rpm PER BARREL.

Hand-held weapons are capable of rates of 45,000 - 50,000 rounds per
minute using 3 round bursts.  

Other than bullet and propellent, there are no moving parts, removing
the most basic obstacle in higher firing rates.

The downside is that ammo comes in long tubes which might be unwieldy
for infantry. (in addition to the fact that you are going to be burning
up a lot of ammo...)
