They have a patent for the system to turn on and of as the train approaches and leaves. This is necessary so that train drivers don't get distracted by the colours coming off the screens. There is also a pending patent for mobile phones to connect directly to commuters phones for Contact Light.

The attractive thing about XTD is that it is a relatively fixed cost model. When they win a contract overseas their only expense besides the initial cost of installing and buying the screens is a couple of workers to run the system. This means that each time they add a country the majority of revenue will drop to the bottom line. On my calculations as soon as they win a train network in say Asia, it will be worth double current levels based on their run rate. I am assuming one overseas deal will have 60% of the revenue of the Aussie network, so its on the conservative side. Just like EML at $1 was a bet on them winning a likely deal in the UK, so is XTD a bet on the likelihood that they will do a deal in Asia. EML has be re- rated to $1.60+ and so will XTD be rerated if they are successful.
