The status of that effort is that there will be a 'raid' target available to dm devices in 2.6.38 which will provide access the md raid5 implementation.
It is likely that this will be extended to cover md raid1 as well in due course.
As features are added to md-raid they would then become available to dm-raid once the dm-raid configuration interface is enhanced to understand them.
i.e. once hot-replace is implemented for md, all that would be required for it to be available under dm would be a mechanism in the dm interface to request it.
