As far as the wushu tourney idea goes. Hax has a point, you can add dojos and ceilings etc, but it's not going to affect the player's mentality towards playing the game (unless you bring it so damn tight together where the mod loses it's point and freedom). There'll be plenty of options to run around, once the advantage by points is gained, while the timer runs out. It especially won't be as effective, for people learning to move around quickly in the mod, which i'm assuming is the target group you've created your versions for (they'll either dq or won't catch up in most cases, rendering the borders useless and without any particular purpose).
Suppose you could make two tourney servers (low belt/high belt), if that's reasonable/useful, one for experienced players (under the assumption that they too, in fact, won't run, which is quite a guess) without the dojo and one for beginners with the suggested cage mod, more controlled environment (even though it has little to no impact to their gameplay/intentions, runners will still run).
You can merely manage the problem that wushu has, not fix it with new mods. That issue requires a different approach. It robs the fun unless i'm actually in the mood for the chase. It sure as hell downgrades your own gameplay and style if you have to put up with that crap every time. Personally i haven't spent much to any time at all in tourney servers just because of that, when i can have fun in some other place. With that notion, it's probably better to *not* include wushu in tourney servers imho, my two cents.
Ontopic though, airhockey.tbm's always fun :>
