LSO (local shared objects) or .sol files will be treated like cookies rather soon anyway. We use them to store certain preferences and information but I don't feel that they will be "untouchable" for very long ...

Unfortunately, client side tracking will be a thing of the past soon. I think the only alternative is URL and sever side database tracking. If the legislators had 1/2 a brain they would just regulate 3rd party cookies and tracking, that is their real intent but it seems like they have no understanding of the technical aspects in this. Maybe someone could clue them in???
