[Zope] PTC and EXIF reading support for Photo product

Hi, I found a product to support PTC and EXIF tags at http://zope.org/Members/ausum/Iptc_Exif_reading_support and I would like to package this for Debian GNU/Linux. Unfortunately there is no license available and so I tried to ask the author Augusto Cabrera <ausum_studio at hotmail dot com> but his e-mail account seems to be full and the mail bounced. Because the product is more than one year old it might be possible that Augusto does not use this account any more and I would like to ask, whether somebody knows a more up to date address. Kind regards Andreas.
