Software to autofold bad hands

[CardMinger]

Is anyone aware if a software exists that reads partypoker hands and autofolds crap hands while alerting you to decent holdings. I am aware that winholdem might do something like this but I am not looking for something to play for me, just something to auto fold hands outside a specified range.

If nothing like this is out there would anyone else find it usefull or would it be unethical to use such a thing?

Thoughts?

Thanks!
