Unfortunately I can't stick to owning or developing Halo so I'm handing it over to someone who can and will. The one I have on ASSS is 25% done but if we modify HSCore I'm sure development can be quicker. I'll plan this out further, but thanks.
Having the player's coordinates would be the end target, but the bomb would have to travel a trajectory for it to get there. That's kind of the hard part.
Agreed, adding a trash talk forum would not attract players to join a forum. Adding something new to the game, however, might... but that won't happen anytime soon.
I'd want replayability... if I come into the zone today to check it out I'd like to come back the next day without getting bored with the same repetitive gameplay. I think Hyperspace is a good solution to this, but the newbies still get left out from all the stacked veteran players.
