I've been suggesting an international LAN here in NA since before i46. It doesn't have to be one of the Multiplay LANs...
TheFragile and I both work with the GXL, which has been around for a long time. It is one of the most successful NA LANs. They have the venue, they have all the networking gear, servers, tables, chairs... Almost everything we would need. We would need to get PCs for people to compete on, since traveling from another country WITH your rig isn't gonna happen, but there are ways we can get the PCs.
Now I'm obviously not suggesting that this go down in October at the next GXL, this would require a LOT of planning. Ill talk to the main guy tho this weekend and run it by him.
PAX is also another option. PAX is a huge convention that hosts a big LAN. We could try to work something out with them as well and make a huge spectacle out of it. That one is a long shot, but the GXL is very, very possible.
Also, just to be clear... By suggesting we do a LAN here I'm in no way saying we shouldn't continue to do the euro LANs. I'm saying we do this in addition to the euro LANs.
