Yea but from what Doug said wireless/IR is not an option anymore as you couldn't do smogon tournaments that way (unless IRL, but...)Oh, if it's misunderstanding what "mechanics" mean you should have said so in the first place.
The Pokemon Company International choosing to use the IR mode is not a mechanic. It's their chosen medium for competitive play. We were under the assumption they would use Local Wireless.
Smogon chose WiFi for Generation V. That had nothing to do with TPCi's choices for competitive play. TPCi using different rules has absolutely no bearing on Smogon's OU metagame. If they did, we wouldn't be playing Singles with only Pokemon that a majority of our best players like.
I have tried to get a full list of what IR can do but the only person I've found on this board with a Japanese copy of the game, the ability to understand it, and access to other people to the game is Chou and he has limited access to that.
If you want to push no team preview, it would be less hypocritical and easier to support if you did the research to find out what IR can do, and put forth an argument for what it offers over WiFi which seems to be our established standard.
So this boils down to what Wifi can do. I've tried to follow OmegaDonuts's possible method, you can see the progress in that thread.
In short as of now it seems like Nintendo will be able to hold online wifi tournaments without team preview (and they will only use that mode, as it seems), but only Nintendo. Kind of ironic.
