Intelligent AltCoin Mining Choices in Real Time

Newbie here.  
cgminer on linux

Any advice on how to easily switch mining between different coins?  Guides?  

Also, is there any program that can help me find the most profitable coin to mine in the moment and then switch cgminer over to that currency?  There's so much volatility in the market, why not try to get the most profitable mining capabilities whenever you can?  

Thanks.

I'm mining with cgminer (altcoins) on linux and am seeing a lot of variability in price between different coins to mine.  One day LTC are worth the most to mine, one day, LTC, and the next, MNC.  I would pay for a program that finds out the most profitable coin to mine (that's the easy part as there are multiple sites telling you that all ready) and instructing cgminer to mine the most profitable coins. 
Only problem is that C# is windows, isn't it.  If you could do that for windows, though, I might be able to get my rig running that.  And I'm damn sure that lots of people would want your product.

I was wondering if there was any way to let my computer automatically watch profitability of different coin minings and then adjust to the most profitable coin. 
ie
Is there a way of checking http://dustcoin.com/mining or http://coinchoose.com/ and, upon finding the most profitable coin to mine, have cgminer change to that coin?  [i'm talking scrypt mining here, but I suppose the same idea would apply to sha-256]
With all the variation in price, it seems like there should be some easy way to do this. 
Thanks
