I would say that the current system is a major inconvenience to 2 button
mouse users, who have lost the ability to rotate. (If 2 buttoned mice still
exist) Also I much prefer my big left and right mouse buttons rather than
the small, highly curved one that wants to rotate under my finger. Tilt is probably the least used movement in aven, so it should be this one that is linked to the middle button, which may not exsist/is hard to use.
I am fairly sure that I would prefer rotations and zooming on the left
mouse button. I end up doing things like trying to zoom by pushing the
mouse left or right, normally, I am slightly of axis and end up with an
irritatingly slow zoom, which takes a while to notice my error. If I saw a
rotation I would know that I was wrong quicker.
The middle mouse button could be free for tilting by depressing it and
tilting could also occur with the scroll wheel. (The window I am typing in
now is scrolled by pressing the middle mouse button or using the scroll
wheel.) It is irritating when you accidentally put a slight tilt on your
cave as it can take a while to notice.
For people with a two button mouse, perhaps Ctrl-right could also work as a
tilt.
It would do no harm to have ctrl and shift left mouse button for just
zooming or just rotating, but I suspect they would not get used much. If
this is done then I suggest that the same modifier is used for 'just
rotate' and tilt, this would be the most consistent in my mind.

The use of Aven differs from computer games slightly. I am suspect that
Aven is more commonly used by more than one person simultaneously (when
discussing a survey more than one person wants to use the mouse), and that
a particular person will use aven on more machines than typical for
computer games. Because of this difference, I think the advantages of
configurable controls would be less significant than the advantages of one
good user interface that is consistent, in aven compared to your typical
computer game.
It is common for people to be come disillusioned with the expo computer,
when they put in effort to work out how to use it, only for it to change.
Cheers,
Martin
