coin split-block mechanics

[biodieselchris]

Is it possible to release a coin that functions with a block reward being split? For example, where some pre-determined % of the block going to the miner as usual and the remainder goes to a pre-determined public address? Is there an alt-coin that exists already that operates this way?

This would be accomplished trivially by mining to produce a coinbase transaction that specifies that result, but as far as it being mandatory, you would have to code the node clients in such a way as to reject blocks that do not comply with that payout. It's doubtful that anyone would participate in such an alt-coin, because all you would have accomplished is a transparently-obvious way to premine indefinitely.

It would be interesting to try it though. Do you know how to code the node clients in that way?
