Litecoin is, like any other alternate cryptocurrency, just a scheme to steal the BTC from clueless newbies.
Just ignore it and eventully it will die out, like others before it died already.
Namecoin was the first fork and still hasn't died.
I suggest you take your own advice and think outside the box (rather than with your wallet.dat) before dismissing all alt. currencies as scams.
But namecoin is not a bitcoin clone.
It can be used as a dns alternative.
