[Accessibility] Secondary Carets needed?

At first glance, it seems obvious that an AccessibleText would only have
one Caret. However I have begun to question whether we will soon need
an ability to represent at least a second Caret. Multi-touch
technologies are allowing users to select with multiple fingers. For
example, instead of defining rectangles by a sequential first and a second
corner selection, rectangles are defined by simultaneous corner
indications of two fingers. The two finger motions of pinch and enlarge
are becoming commonplace in multi-touch interfaces.
Thus I wonder how long it will be before there is a requirement of text
selection from simultaneous touching of multiple points, thus creating a
need for two or more caret references in a linear string of text.
Please excuse me if this is an old topic that has been soundly considered.
