I'll say up front, I love GISkismet for interpreting kismet .netxml output for sending to Google Earth. However, I find that sending the .nextml output to Sqlite3 also gives me plenty of options for reporting on issues as well!
In many cases when I do assessments, I won't have GPS location available; I'm walking around inside of the assessment environment without a clear view of the sky. In this case, this gives me the ability to see the environment just like the clients see it, often times revealing some risk that is oft forgotten about.
