If you go this route, be sure to take a look at the custom column comparator I wrote to make this sort of thing easier:

You could also use a standard column family, composing the version
into the column name:

 foo => { bar:v1 => data, bar:v2 => data, bar:v3 => data }

Here, there's a cost on retrieval of course, which may or may not work
depending on your access pattern. If you do large slices, it's
probably not an option. It could be feasible to write a custom
comparator sorting on some version component, to allow efficient
slicing of the "latest" versions.
