Many Android devices support USB input devices - both my Galaxy S3 as well as my Nexus 7 happily accept USB keyboards even when requesting the encryption PIN during bootup. I programmed an ATMEL ATMega32U4 (microcontroller with USB interface) with a simple program that iterates through every possible PIN, waiting for 30 seconds after 5 or 10 tries. If the system continues booting, the controller recognizes this by "pinging" the CAPSLOCK LED: if "hitting" CAPSLOCK does not change the LED state, the system has started to decrypt the device because of a correct PIN, which is then stored in the devices EEPROM. I created the device using an teensy development board and the LUFA framework. Not as spectacular as a robot, but effective as well.

Are you aware that in Switzerland they GIVE EVERYONE automatic weapons and a bag of bullets?

This is not completely correct. After (compulsory) basic training in the in the swiss armed forces, you stay part of the service; you are placed on "stand by" and are required to keep your personal firearm at home, so you can defend yourself in case of a sudden invasion until reaching your mobilization area (switzerland has very interesting topology that might make this complicated). Up until recently (a few years ago), each service men also received a *sealed* package of ammo, which had to be presented intact on a regular basis.

Back in the days, you had online services offering messaging , games and information services - but only for those using the same company. Then you had the opportunity to use a gateway to this internet thingy.... Now we are getting back there, only the other way around: Facebook & Co are offering messaging, games and information services: But only to those signed up there. Facebook and the other social networking sites are the new online services, island that are completely isolated from each other.

Of course you can use arp poisoning on a WPA2 connection, as long as you have access to the broadcast domain. This means either a valid WPA2 passphrase to connect to the network via air or access to the wired part of the network (which is usually bridged). Remember: WPA2 encryption is only a way of preventing anyone from connecting to your network, it is not a sufficient way to protect your data: What use is an encrypted wifi link if the data is travelling the next 1000 miles beyond that purely unencrypted? Use HTTPS/TLS/SSL/SSH/... whereever you can!

I've never actually talked to anyone playing the "evil" way in Fallout 3 - it seems that even though everything is purely fictional, some rules of society still apply. Perhaps its also just an experience from past games that "noble" conduct usually was rewarded later on. But I even sometimes felt bad when the game did not offer a "common sense" solution and I had to resort to deadly force (Why do I have to kill the Overseer?).

There is a location here in the city of Essen, germany that resembles your idea: It's a building housing an interesting combination of a restauraunt, art studio, electronic laboratory, stage etc. You can use most of the equipment for free, provided that you do it openly and thus allow spectators, each paying an entry fee of 5,5 EUR which includes an unlimited supply of coffee and soft drinks. Quite nice for hanging out, learning for an exam or soldering together some new devices. Of course, WLAN connectivity is available as well :-)
