What about a relay race where cargo is picked up at one station but must get to another station?

The cargo would explode after a preset time limit unless jettisoned. Say you need 4 people on a team (A group). (Perhaps the first wormhole jump activates the timer, so the race would be 4 systems long for 4 players on a team.) Once one person jettisons the cargo he/she cannot pick it up again.
Another player must get the cargo and continue to carry it to the destination.

Be more fun if bots were also after the cargo while racing. Fast bots in Vultures or something.

Gotta flesh this idea out somewhat.

You've checked out "Capture the Cargo" right?
