Moving targets

Regarding “Sprint supports GPS technology for tracking school buses”: This is old hat -- obsolete technology. For about $1 per day, USFleetTracking has been providing a tracking service for quite some time to the masses. The system has been deployed in police departments, ambulance services, on school buses and business fleets -- even in teenagers' cars. Even better, the USFleetTracking system is a real-time system. It updates the positions of thousands of vehicles live at five-second intervals. You see only your vehicles, but a business fleet can have hundreds or even thousands of vehicles tracking on the map at once. Move the mouse over the vehicle to see how fast it's moving. Zoom in to see precisely what lane the vehicle is in. It's accurate to within about eight inches. Go to www.usfleettracking.com and have a look at the live demo. Those aren't pre-recorded vehicles moving around -- those are actual sheriff's deputies in Oklahoma City, and it's live, showing where they are at the time you're watching. You can even go into hybrid view and see aerial imagery, or zoom all the way down to see the specific house at which a vehicle is parked.

They have thousands upon thousands of vehicles on their system, and from what I understand they're the biggest system of their kind in the country.

Role-playing

Regarding “Exchange 2007 integration issues arise”: During development of the Microsoft Exchange 2007 version of Azaleos’ managed e-mail appliance, our engineering team evaluated virtualizing Exchange roles, as we thought it was a great way to try to reduce some of the cost and complexity of the multiple different ways to deploy roles with Exchange 2007. At our blog site (http://www.azaleos.com/blog), we've noted more details on what our engineers found and what led to our scrapping plans to deliver an appliance via a virtualization approach.

Telecommuting tradeoffs

Regarding “Telecommute. Kill a Career?”: I am a telecommuter and work out of mobile office. I work in three states and handle large enterprise customers. I don't think telecommuters or mobile office workers will experience career killing. I think mobile workers select their positions because of their skills, talents and love of interfacing with customers. I believe mobile warriors are the wave of the future and these people tend to accept and fill these positions because of their nature.
