That's what 'bitcoin-brokers.org' does.

I'm guessing that the fun will come to an end if/when it becomes unlawful to deposit cash into a random person's account without some modicum of 'know-your-whatever-ness'. I'm surprised it's even allowed now to be honest. Probably it would be implemented by some combination of claw-backs and/or banks just shutting out customers who do this. My guess.
I forgot about that ... sure, if cash deposit in China works, then Bitcoin-Brokers.org or similar service there would work pretty well. That is .., until they start confiscating funds of people caught selling coins that way.
I wonder if cash deposit (by a third party, without providing identity) is an accepted method in China.
