FBI visit Second life!

It seems it's not just academics who are visiting Linden Labs' Second Life. The FBI have reportedly visited casinos in the virtual world to assess their legality, given recent changes in online gambling laws in the States.

Someone on a gaming forum I frequent asked in disgust whether they'd be taxing people for moeny made in virtual worlds next... but I'd assume that if you are converting income in Linden Dollars into Real Life money then you should probably declare it in your accounts, but if you don't convert it then what?

Anyway - guess this is an example of people playing at gambling, but who may actually be gambling... if you get my drift ;)
