This is a great segue for the "pump and dump" scheme. Essentially you can create your own coin and mine it with your buddies. Then create a mini exchange for the coin and target the older, less tech savvy people - who won't be able to tell the difference between Bitcoins and a more obfuscated virtual currency. Basically you'll accumulate the virtual coins for free and sell them off for a profit. Maybe I'm missing something but it feels like all the ingredients are present.
