BMW Interactive Test Drive with UMap and live video / BMW Interactieve Proefrit

I've just finished a project for the new BMW 3 Series. Visitors of the site can subscribe for an interactive test drive. During (dutch) working hours live video streams are being broadcasted from the cars using UMTS and Wowza media communication server. Also, GPS coordinates are being sent to trace the position of the cars. The positions of the two BMW's are constantly shown on an interactive map, made with the UMap component by www.afcomponents.com together with text messages that the test drivers send after their drive. People watching the live streams can also call the cars to talk to their current drivers.
