My client provides in-flight broadband satellite service for business aircraft passengers. We are looking for a way for our aircraft passengers to synchronize their BlackBerry Devices during flight. The passengers do not have access to a cellular network, but they do have internet access via VPN. Also, the passenger do not have a laptop.

How can they synchronize their BB devices with a hard wire synch through the VPN connection?

How can they synchronize their BB devices with a wireless synch through the VPN connection?

Any assistance is greatly appreciated.
