I am hosting an official Windows 7 launch party. What activities should I organize?

I'm one of the lucky many who have been selected to host a Windows 7 launch party, but I want to take it above and beyond the suggested themes of "setting up your email" and "burning a music CD." I have a few ideas for "cool" things I can show people regarding Windows 7, such as how to install it on their Macs with Boot Camp, how to set UAC appropriately, how to dual-boot with another OS, and how to move their documents and pictures folders to a separate drive or partition, but obviously these ideas are lacking in the fun department.

What activities would you plan to help make this geeky party more fun? What Windows features should I teach my attendees? What third-party software would you have me recommend them install to better enjoy Windows? Thanks ahead of time.

*Note: I want this to be a subversive party. I'm not a fanboy. I'm not selling them Microsoft music services, I'm not convincing them to buy Zunes, I'm not telling them to switch to Hotmail (or whatever Microsoft calls it now). I don't mind showing them how to install Ubuntu. I'll show them how to use torrents, teach them about private trackers, how to Internet like a pro, et cetera. I'm not inviting computards to the party, but helpful suggestions to make people better Windows users are appreciated.*

*Note 2: It sucks to be downvoted by haters.*
