Distributed networking means that a wily player such as myself can assume your FE responsibilities, so your inputs are telegraphed across the internet to my machine, hence the sudden delay.
That is weird. The only thing I've seen similar is the game's sudden habit of going to slideshow mode. I figured out it was because I traditionally have the HTC UBB running in the background, and they recently changed their method of putting adds up. Now ever x minutes you get a 100k download.
