But with things like the wiimote, such devices will perhaps become more common.

That's what we would want to do, but I wanted to know if there is any
work on 6dof api in Blender now.

We do not want our patch to have any connection with either 3dconnexion
devices or any other devices like that. Just an API.

And a lightweight API, if there would be an external  6dof server.

In my opinion, Blender should not have to handle dynamics or speed of
the 6dof device, just like a normal desktop application does not
handle dynamics or speed of a mouse cursor. Thus, I propose an
external not-Blender-specific server, because X Window does not handle

Blender would connect to the server to get 6dof just like it connects
to XWindow to get mice position.

The server could translate 6 * velocity devices like SpaceBall or 6 *
direct position devices like Wiimote, or any mixed devices, into 6 *
direct position data to give the data to Blender or other clients.

The server would have a configuration GUI, and the protocol would be
very simple.

Just please tell me if this is OK, and we will try to make the server
and the patch.
