As far as I am aware although the project has been given the Green light, there's been nothing announced to the staff about it.
Have you tried TrainFX? as they would be your best bet as they are installing it plus I believe they installed the Volo stuff in the FGW sets.
I think to be on the safe side as I don't intend to get into trouble with my employers at the moment is just discuss the general idea of what the project could be like, I will need to leave it to FCC to officially announce anything but the general ideas are as follows:
Key features and benefits of this scheme include:
Robust and flexible network infrastructure, able to receive real time and near-real time updates.
A key benefit to our customers will be the ability to see real time passenger information during times of disruption. This will include scrolling ticker based text messages relating to service disruptions and/or security alerts.
Our customers will also be able to view the latest London Underground Tube running information, timetable information and transport connections, ready for their arrival at our stations, thus aiding customers with their journeys.
Not to mention the latest news, weather, sport feeds etc provided from the BBC and Sky.
Now all this sounds good but I'm guessing it's the same setup at Kings Cross with the large screen in the main concourse presenting the latest news but on a much smaller scale.
Now as much as I would prefer better mobile phone reception on our trains as opposed to free wifi, I suppose this would be the next best thing.
