What really surprises the living crap out of me is that you're attempting to find a technical solution to what is essentially a social problem. If you really want to do something to fix this problem, as you describe it, try suing microsoft for lost time/man-hours/profits/whatever due to their lax security practices instead of mucking about with DNS/ICANN/whatever else.
Wasn't going to comment on this thread as I really can't add much (as I read the entire thread bemused as I still don't see the prob even when i learned abou this zero day days ago) but amen to Allen's comment here. There are multiple issues here and DNS and / or $insert_favorite_technology isn't the problem. On completely OT side comment for laughs: why is nobody blaming the real root problem here ... marketing folk and their insistent drive for multimedia for sales reasons (e.g.animated cursors and HTML email) :)
