Before you get started not that tracking type applications require a Bing Maps license as they do not fall under the free Terms of Use for Bing Maps even if they built using mobile devices.

As for doing what your looking to do you will want to create a web service that can take in the coordinates and store them. A typical architecture consists of a client application that is installed on the GPS device that sends the coorideates to the web service, stores them in a database. A second webservice or a second method call in the original service is then used to request the latest coordinate from the database. This coordinate can then be easily requested by another client application and displayed on the map. Note that you can also store the coordinates over a period of time thus allowing you to do replay and rewinding of the data which is useful in some commercial applications. Also, it should be noted that these types of locations do not need to transimit the GPS coordinates very frequently, once every 5-15 minutes is usually more than enough.
