You have to consider the following: If the guest additions are not available,
the guest is not able to receive absolute mouse coordinates, only relative
mouse coordinates --- at least with the mouse VBox is emulating. Therefore
some switch between the host mouse cursor and the guest mouse cursor is
needed. This cannot be done with auto-capturing since the state transition
cannot be that smooth as needed. The real problem is therefore to emulate
a pointing device which supports absolute mouse coordinates.

Kind regards,
