From the website:

The LapSnapper Pro Clients communicate with the LapSnapper Pro Lap Timing System via a Wi-Fi service. LapSnapper Pro Clients are able to show, record and save lap, sector and split times received from the LapSnapper Pro Lap Timing System. LapSnapper Pro Clients are not able to host race, qualifying or race sessions.

Unless they are planning to do some software upgrades, this system is useless if you want to use it for races.
