Well, from the above mentioned post (I know nothing apart this),
1) is still work to define ... and start,
2) writes data to files in <current dir>/telemetry,
    once the code in rtelem.cpp is no more commented out,
3) writes data to the console.

One more thing : I'm not sure, but I had understood that Kristof
intended to extract data from the physics engine, and Simon, you seem
to be talking about something more related to "real-life" telemetry.
Should these be implemented in the same code or not ?

Kristof, do you already have a more or less clear view about
how things could be implemented inside SD code ?

As for the SD to external telemetry tool channel,
you're right Simon, you could well use a socket connection,
or even a simple pipe (both are portable).
The socket option would even enable the external telemetry tool
to run on a different computer.

Cheers,

Jean-Philippe.
