Ok. I assume you will also have object manipulation on the list? This
would be essentially the reverse of all other modes: 3dview navigation
with 2d mouse, object translation and rotation with the device (don't
think scaling fits in this picture well enough).

I'd put code that uses this in the places where you have it now (ie
3dview). That way it makes sense to have these as user preferences, and
they would be accessible in all useful places. No need to figure out
different ways to save those between session then will be necessary
either - provided the user remembered to callibrate ie for sensitivity
first, then save user prefs.

I guess it would be great to have such settings saved separately from
all other user preferences, but right now I wouldn't put energy into
coming up with a way to do that. Rather keep it consistent with current
user prefs, and after integration is complete, work on a proposal to
make a division of logical parts of user prefs and have them saved
separately (as has been discussed several times on ML and in IRC).

For fly mode, dominant axis, and other modes I don't think it is
necessary to persist those between sessions.
