Jolu shrugged. "Maybe that's why she's so freaked out. Because she knows how dangerous it can get."

I knew what he was talking about. Two of Van's uncles had gone to jail and had never reappeared.

"Yeah," I said.

"So how come you weren't on Xnet last night?"

I was grateful for the distraction. I explained it all to him, the Bayesian stuff and my fear that we couldn't go on using Xnet the way we had been without getting nabbed. He listened thoughtfully.

"I see what you're saying. The problem is that if there's too much crypto in someone's Internet connection, they'll stand out as unusual. But if you don't encrypt, you'll make it easy for the bad guys to wiretap you."

"Yeah," I said. "I've been trying to figure it out all day. Maybe we could slow the connection down, spread it out over more peoples' accounts --"

"Won't work," he said. "To get it slow enough to vanish into the noise, you'd have to basically shut down the network, which isn't an option."

"You're right," I said. "But what else can we do?"

"What if we changed the definition of normal?"

And that was why Jolu got hired to work at Pigspleen when he was 12. Give him a problem with two bad solutions and he'd figure out a third totally different solution based on throwing away all your assumptions. I nodded vigorously. "Go on, tell me."

"What if the average San Francisco Internet user had a lot more crypto in his average day on the Internet? If we could change the split so it's more like fifty-fifty cleartext to ciphertext, then the users that supply the Xnet would just look like normal."

"But how do we do that? People just don't care enough about their privacy to surf the net through an encrypted link. They don't see why it matters if eavesdroppers know what they're googling for."

"Yeah, but web-pages are small amounts of traffic. If we got people to routinely download a few giant encrypted files every day, that would create as much ciphertext as thousands of web-pages."

"You're talking about indienet," I said.

"You got it," he said.

indienet -- all lower case, always -- was the thing that made Pigspleen Net into one of the most successful independent ISPs in the world. Back when the major record labels started suing their fans for downloading their music, a lot of the independent labels and their artists were aghast. How can you make money by suing your customers?

Pigspleen's founder had the answer: she opened up a deal for any act that wanted to work with their fans instead of fighting them. Give Pigspleen a license to distribute your music to its customers and it would give you a share of the subscription fees based on how popular your music was. For an indie artist, the big problem isn't piracy, it's obscurity: no one even cares enough about your tunes to steal 'em.
