Need IP Address in download file

First, let me say "Thank you" for this module! It is wonderful, and much better for our needs than the Survey module.

The form is running at http://www.jvibe.com/MusicAwards

The site editors are thrilled that they can view the submissions and analysis online via the drupal interface. (Last year, I had a hand coded form, and I needed to download the results (also in a csv file) to keep them updated.)

My support request is:

The submission IP address isn't included in the downloaded file. It is displayed in the submissions tab, as well as the table tab, but not in the download file.

Even though we ask people not to vote more than once, we find that some people will ignore that, so I use Excel tools to remove obvious duplicate votes. Having the IP Address helps to find these, and would be very useful. Last year we received over 1000 votes, so I would prefer to do this analysis directly in Excel.

(we understand that some people may share IP addresses (same office/household), email addresses (family email), or names (some people don't have unique names) but patterns can be detected if there are several votes that are identical with one or two of those fields identical.)

Thanks in advance for helping with this. Please let me know if this is a "feature" request, rather than a support request.
