err hawk you do realise you could easily have hosted them without warzone on your lan. I've done this myself, all you need to do is go on the built in multiplayer built into tak and create a game there, the others can then join + you wouldn't need bypass.
If you don't have the cd just download tak switcher and use pgtak.exe for every player, that way you can host a game without the cd.
warzone is ridiculous though, i thought the whole point in moving from gs to wz was because warzone "cared" about tak, well tak has been in this state for ages with no change, that link must be taking a long time to delete.
