difficulty monitor and auto switcher ?

[bitkokos]

Hi
Is there any software where I can put 2-3 pools of different scrypt coins and it will monitor the difficulty and switch to the coin with the lowest diff?

I mean if the diff of coin X is lower than 10, mine it otherwise mine LTC. If later the diff of coin X drops below 10 switch back to coin X.

I am interested about cgminer on windows or raspberry pi (preferable)
