FBI investigators have visited Second Life's Internet casinos at the invitation of the virtual world's creator Linden Lab, but the U.S. government has not decided on the legality of virtual gambling.

So much about this quote amuses me. On a serious side, this begs the question when is "virtual crime" real crime? Is virtual gambling taxable? I would assume only if you can somehow get real money out of the game. Which leads us to eBay restricting the sale of online items or characters, the classic way people transfered money into the real world.

I wonder if they'll start cracking down on all the "virtual" prostitution in SL.
