Hi, I don't completely understand your comment.  Anyone can run the
tool irrespective of whether they are sitting on a network that
blocks spoofing or not.  In this case, the user's test results will
report that no spoofing (among all classes) is possible, and 
where filtering is in place.  (And the summary results will 
reflect that the netblock is believed unspoofable unless there
is evidence otherwise from a different test).

Are you saying that there's an implicit sampling bias in the
results?  Clearly users may be self-selecting, but the networks
they are attached to are not necessarily so.
