That is pen data. Handwriting analysts use that data
as well. The coordinates aren't different; they are
providing data about the individual style or technique
of the strokes. I can envision applications for that
in the public safety industry where proof of identity
is a substantial issue and loosely coupled systems have
to exchange records while managing a single process.
Think prisoner processing such as booking and release,
evidence handling, citations and writs, and so forth.
The NEC declaration could stop it dead in its tracks.
As the IP situation has grown evermore explosive, it
is degrading the ability of the middle tier vendors
to adopt open technologies. In other words, better
to buy and license than adopt and wait.

Good to hear.
On the issue of coordinates, I think InkML may at least have a case that
its coordinates are different from others.
Take a look at the table in:
http://www.w3.org/TR/2003/WD-InkML-20030806/#traceFormat
They're including tilt, yaw, pitch, pressure. Lots of stuff beyond
coordinates, though maybe this is really describing vectors, not
something necessarily specific to pens.
