Socket location without IK

Is there any way to get the location that a socket would be in without an applied IK?

I am applying an IK to a hand bone to align it with a surface in worldspace, but I want the animation to continue relative to the IK. It works automatically with a bone space IK but I want to be able to use a world space IK for ease of calculations.

If I understand you correctly, you could take a spare bone (one of the ik bones maybe), copy transform from hand to that bone, and place the node before your ik node. Transform of that bone will be what you need.
