Hi Daniel,

As Alan noted, NDT currently only works with web100, and not web10g. However, 
Richard Sanger has produced a set of patches for using NDT with web10g. I've 
cc'd Richard who may know the current state of the patches (I've attached the 
most recent copies I know of), and which version of NDT they apply to.

Cheers,
Aaron
