Benjamin Tissoires and I have been working on a project called Tuhi that communicates with the wacom smartpad devices and pulls the data off them.
https://github.com/tuhiproject/tuhi/
Devices working so far are the Bamboo Spark, Slate and the Intuos Pro Paper. Smartpad devices aren't traditional graphics tablets [1] but instead have a paper notepad on top of a sensor with a special pen. You draw on the paper, the sensor registers the drawings and stores it in a custom vector-based format in the device. Later, you connect the device over bluetooth to the host and fetch the drawings from the firmware.
This is the bit that tuhi does, and it exposes the drawings as a simple json-based vector format overa session DBus API. To interact, you basically connect to the dbus daemon, tell it to listen to the device and then get notified about new drawings. Then you can fetch the drawings one-by-one as needed.
Tuhi only has a commandline client for debugging and we don't intend to ship that client, it's for debugging only. Eventually, we may have a standalone application similar to Wacom's Inkspace (yeah, confusing, isn't it?). This app would be a gallery-style application that displays the drawings and exports them to the desired formats. That's a fairly straightforward process.
But right now what we're interested in is whether inkscape has interest in a plugin-style implementation that talks to the tuhi daemon. Or whether there are use-cases where the standalone application is insufficient and some tighter integration is needed. Or other use-case you can think of that we haven't yet.
Any comments appreciated!
Cheers, Peter
[1] the intuos pro paper is when you plug it in, let's ignore that for now
