No hard deadlines at all for now, this is just an elevator pitch, and this is NOT an "official" 4CC thing, although the 4CC is also OK with sending an All-Star team (if someone can manage it).
Solo proposal. It's a thing I've been mulling over for a number of years (since I also have ties with some italian *chans) but never acted upon until now. I did see the GCUP but I think your concept is more like Dag's Multinational Bowl than an inter-chan tournament like I've been wanting to do.
Anyway, that cup is part of the reason the ball got rolling in the first place; during it I talked about the meme world cup to someone from Kraut who expressed interest, and then someone from ylilauta caught wind of it and mailed me so they're now in the process of building their own team, so I thought I'd ask here and at the 4CC's commissioner as well too.
As for being on 17, I wouldn't worry too much about it. Porting aes to 18 to 21 format is not exactly automatic, but it can be done.
