I do not see this as much of an issue/problem for widespread 
exploitation of this.  Recall the (modest) "success" of the MindJail 
virus, and the ongoing success of Mijail (which is by far the most 
prevalent mass-mailing virus this month if you ignore the Sobig.F 
freak).   Both of these viruses exploited a "My Computer" zone-only IE 
vulnerability, depending on the typical handling of files from inside 
archives being placed into %TEMP% despite their source archives clearly 
being handled in the TIF.  Of course, MS (and thus IE) cannot manage 
third-party programs handling of files passed out of of IE's security 
zones...
