I agree with Martin: the object of the analysis is to determine weaknesses
within the environment. However, it is feasible to avoid 'destructive'
scanning with appropriate preliminary network analysis in concert with
predefined procedures and expectations.

Tell them that the purpose of the test is *to test* (i.e. to try
something) and the only thing you can do to not break anything is to
not try anything at all. Maybe they want an audit instead of
a pen-test and they just don't know the terms and the meanings.

If they are so scared, negotiate the exact time of potentially
destructive/aggressive tests.

Use Nessus with "safe checks" turned on for "polite" scans... You can
also disable all "DoS" family plugins in Nessus.
