Hmm, I think that'd be pretty interesting too..
And as far as free venues go, It's a nice contribution by you Mike. However, a venue like that conference room in the Student Union is more suited towards more casual, smashfest-esque events. For a larger event that includes tournaments for a variety of games as well as a casual area would require a much larger setting.
In the past, I've seen few such events that took place in venues such as the Egan Center, the Sports Complex out at Kincaid, the Marriott and the Seattle Center. Don't get me wrong, a gathering of the smash community at your house for smash and a barbecue in your backyard or something would be absolutely great. (I'm actually kinda bummed that I might miss out on such events this summer.) However, a larger event that would include multiple games and people outside of out tight-knit community would be alot of trouble for you to hold at your own home. Might be quite the inconvenience with others residing there too.
Just saying, free venues are great to have as an option. However, we might be dealing with something that is beyond the scope of that.
