his should work fine, but it requires you to disable the "sync mouse"
option and use a scaled (compiz drawn) mouse cursor. This allows the
mouse to move freely independent of where the zoom area is (though
mouse panning is recommended). I assume that's what you're looking

I use this myself, but let me warn you that it is affected by a bug in
xfixes. On certain cursors, most notably the "loading" cursor of
firefox, xfixes isn't able to give us a usable mouse cursor. The
immediate result is that the cursor disappears when these pop up. What
makes this bug even worse is that once you've started hiding the
cursor, this bug will happen even after you've stopped zooming.

However, eZoom does have a small hack to reduce this effect. It checks
cursor data, and if it detects a bad cursor, it retains the previous
cursor, so if you're zoomed, this helps you quite a lot, even though
you might see the WRONG cursor, at least you're seeing A cursor.
