There's always the GOOD and BAD from ever technological advance, it's the 'technology paradox' IMO. There could be a middle ground that everyone is missing, what about an OPT-IN approach. In this OPT-IN approach, people who opt-in would receive the benefits of the new CVIS system either through special lane assignments (a la HOV) or purpose-built roads (a la toll roads). Both of these are opt-in 'systems' and offer the vehicle operator the choice.
These systems would be options or even installed by default yet the owner would choose to opt-in or not. The trick would be this opt-in is not a daily choice but something one would do either annually or bi-annually (like registration or registration renewal). One would receive a code to 'log in' or authenticate. Data collection should be transparent meaning the vehicle owner has the ability to view the data collected. Data archival would also require some thought -- ie, can it be made anonymous in some way like removing the unique identifier yet allowing the data to survive for analysis & trending needs.
Much to do here yet let's not be completely Orwellian.

If you look into Novell's Distributed Print Services (NDPS), you will find that "print servers" as we know them are no longer necessary for NDPS-aware printers. In fact, more than a few printer companies will be releasing NDPS-aware printers end of this year/early next year. With NDPS software embedded into printers, you won't need a print server at all.
