I kinda miss the feature on where you could watch someones fileshare while you waited for the game to start (while map vetoing).
This feature was on Halo 3, but it wasnt on Halo Reach, well I dont remember really but either it would take a dozen of seconds to download a screenshot and watch it, or there was simply no feature as this one at all.
In Halo 3, right before vetoing, all I had to do was click on the player, view file share, and the screenshot would come up in seconds.
