Hi - HDK question...

Is there a reliable way to determine if a SOP input has changed at all?  
I'm using duplicateChangedSource(...) and fetching the 'changed' flag, 
but the flag returns 0 if i just transform/edit the input points.
I'm writing a three-input deformer SOP, and there's a whole bunch of 
heavy processing that only needs to be done if either of the first two 
inputs have changed.
