Re: DGM pools -- bitparking, EMC, etc.

If so, then for 1 share that I submit, I am to receive both 1 unit of reward for bitcoin mining, but also 1 unit of reward for each of the other coins.

Yes, that is how it works: http://bitcoin.stackexchange.com/questions/273/how-does-merged-mining-work

So, if converted (at today's rates) to bitcoins, what is the total reward per share on a PPS system (assuming 5% fee on bitcoins and 2.5% on all others)? In other words, what is the sum, in bitcoins, of all rewards received?

Right now namecoin adds 8.13%, devcoin 0.62% and ixcoin 2.18% to your earnings in terms of the price ratio to btc.

And with that math if I'm not mistaken, if all your after is btc then this pool is paying out in excess of 100% compared to a btc only pool even with fees....
