Well, the main tv in the house is busted and it doesn't have s-video so chances are we're not going to be using that. If anything, we'll be relying strictly on monitors and laptops. So, a list of things to bring:
converters, laptops, power strips, speakers (if you're bringing something other than a laptop), monitors, sticks/controllers.
If I rearrange everything there should be enough space for all of this. I'm guessing 4 complete setups should be enough. Post up if you can donate a setup with any of the above materials.
