Teagueduino will run the code anytime it has power over USB -- communication is only needed while programming/debugging. With a USB battery backup, you can run self-contained projects. http://www.amazon.com/5000mAh-External-Motorola-Blackberry-N...

We've also been thinking about integration of wireless. It quickly makes things more complex and expensive (unfortunate for beginners and education/schools), but enables lots of cool projects (especially vehicles and remote automation). In the meantime, you should be able to use a wireless USB cable setup if you want to remotely program/play with it: http://www.amazon.com/Cables-Go-29570-TruLink-Wireless/dp/B0...
