Well I'll be damned... Nanoweave works with NMG. Meaning nanoweave does affect overshield. Just tested this by multiboxing on PTS: http://imgur.com/a/dC5O0 I equpped Mauler with slugs (500 dmg) on my NC engi, and NMG on my TR. Activate the shield on TR and quickly switch to window with NC to shoot the TR, then switch back to TR to deactivate the shield and screenshot. You can see whether I have Nanoweave equipped in the chat window. This method of testing is not perfect, but you can clearly see that overshield takes less damage when Nanoweave is equipped. I have no idea why nobody else bothered to test this before, it's so easy. I just took on faith the common knowledge. Holy ****... We still have yet to figure out just how much energy the overshield has and what are the activation and upkeep costs are, but roughly it's 600-650 energy after activation. Meaning at least 1600 * 1.25 = 2000 effective HP. This is just disgusting.
