Awesome! I was fooling around with Quake II, and I had the Zero connected via USB to my laptop. Started Quake II on my laptop, then started a multiplayer server on the Zero and... connected to it on the laptop! Death match! Can't quite get it to work wirelessly yet, but I'm sure it's just something I'm doing wrong. Who cares? It works!
EDIT: Still no wireless, but I did some experimenting and it seems that FileZilla must be connected to the Zero via USB (10.1.1.2) on the PC you plan to link to the Zero. Makes sense. I wonder, does that mean if I'm connected wirelessly via FileZilla will the PC Quake II will see the Zero's Quake II Server WITHOUT USB? I've already tried using the PC's Quake II to connect wirelessly to the Zero's IP address, didn't seem to work. I'll give it a shot later on. Interesting, though.
