Namaste Bhai Saab
Phone Your new ISP and ask them directly if they are shapeing P2P traffic
if they are and you want to use LimeWire, You will have yo change again.
Make sure you ask the new one before you sign up for it.
If they say, they dont shape,Get back to us, Be pushy sometimes they distort the truth, ask for written statment.
Peace.
