So far there is no block stripe (RAID-0) component. I have, however,
implemented a minimal block mirror (RAID-1) component [1], which could
be extended to also support stripping (being able to just provide a
nested RAID configuration, i.e., stripped mirror, and the component
would figure out the rest would be nice but I will not have the time in
the foreseeable future to implement it).

That being said, building a simple block stripe component from scratch
is not hard and starting with multiple components and figuring out how
to combine them afterwards (keeping them seperate or integrate them in
one component) might be better than extending one prematurely.
