As you can see in the screenshot, items are not being shared between game instances yet.
The type, position, speed, heading, armament, animation, and killed state of characters are sent between games. The position of network characters are dead-reckoned based off the speed and heading of their last update packet to keep the movement smooth and limit packets on the network.
I'm actually quite happy with how smooth the motion is over the network. It's on par with similar network games. Up next will be to send effects and items over the network.
