A little of each.


Yeah, I have no immediate plans to get rid of namecoins. But litecoin doesn't support merged mining. I think the whole point of litecoin was to make CPU mining viable again, which is a bit of a strange motive for starting a new currency.

If I add Litecoin then you have to choose between mining Bitcoin+Namecoin or Litecoin. Or you could put some of your hardware on Bitcoin+Namecoin and other hardware on Litecoin.
