How have people been working initiative/activation with multi-player teams a-la Op Cerberus mission 5?

Do you all roll dice and activate in that order (rerolling draws) or roll for Axis and allies then pick a unit as normal, fighting within the team to see who gets to go this turn?

I believe your second suggestion is the official way to play. I've seen it suggested somewhere to have both of one side go, and then both of the other side go, allowing for the possibility of co-ordinated attacks, which could also be a fun way to play.

The game is a bit boring and slow if each side activates one unit in turn, to much talking in what to do next and waiting for your turn, we always player that all players of one side activate at the same time.
