Yes - Castle Link Live was released with firmware ver. 4.01
We are in the process of working with various Tx mfg to get there protocol so the ICE esc's can work with there telementry.
In the mean time we do have a document that explains how it works & a few electronic savvy modelers have taken that info & gotten certian Tx's to display the data from the controllers.
An example of this at play can be seen in the Traxxas XO 1. All the telemetry data seen on the iPhone or iPod docked to the Tx is coming from the Castle Link Live in the controller we make for them.
I am attaching the info if you would like to take a look at it
