If one finger is stationary, it is trivial to find out where the other
finger is using the available semi-mt data.
The general feeling about this patch is that it is very similar to
where we started off two years ago. The problems we saw then led to
the implementation of the semi-mt protocol. I doubt things have
changed much since then.
