Dunno guys, but keep in mind that namecoins aren't "money". There is a bunch of namecoin threads so I first suggest you look at those.
BTC isn't money either but you can trade it for money. It all depends on the current market value of the asset you are trading for money.
Find the market value of bitcoin and namecoin then figure out how many you can mine each day (at current and projected difficulty levels), multiply by the price and you will have your answer.
