You can have bitcoins generated directly to your address by mining at a pool that does it's payouts like that. P2Pool and Eligius might be the only ones, here's an example of an Eligius payout. But that's still not the same as having the whole block reward generated to you.. or is it? I don't really know what's the value-adding thing here.
The value add is in finding the morons willing to pay over the odds for a bitcoin block and as I expected the usual suspects are in with how great this can be hold onto your wallet their at it again...
