MS?
I'm sure there is a program out there like SC that can do that.
www.google.com is great place to start?
There is a hack out there that is like an auto-pick up. Its not too bad yet since each kill you make the items are yours for a while. When that timer is up the item(s) are up for grab. The hack just waits for the timer to go off and then "grabs" all the items in the area.
