Eclipse mining lets you mine for both namecoins and bitcoins. But does your miner's processing power have to allocate half to each if you wanted to do both at the same time?
No, it reuses your hashes. It's free money.
Thanks. Was arguing over this on a different board.
There appears to be other online currencies starting up as well...Litecoin, Devcoin, IXCoin, I0Coin, Liquidcoin...will any of these work with merged mining as well?
the same proof of work is submitted to the different *coinds
BTC and NMC use a different algorythm to Litecoin, Devcoin, IXCoin, I0Coin, so they cannot be merge mined together
the scrypt based coins could be merge mined to work with the other scrypt based coins if the work was done to make it possible
