ofcourse you could mine LTC... but also look at FTC...
going for about 335 FTC = 1 BTC at the moment..
Where's that being exchanged?
Based on current exchange rates:
~.06LTC/FC:

https://btc-e.com/exchange/ltc_btcYou'd be looking at:
~16.7FC / LTC
~33.3LTC / BC
~555FC to get one BTC, minus exchange fees.
If my math serves correctly, at the current BTC/USD rate of ~$123, that'd put an estimated value of ~0.22USD/FC
