Hi Chris - you could use the "Cut Plane" plugin for this:

- apply the plugin twice, once with ExtractVolume=1, then with 
ExtractVolume=-1

- merge the elements from both views (View->Combine Elements)

- save the view as a mesh (View->Save as)

However, the quality of the resulting mesh will most probably be very 
bad (since you might split elements arbitrarily close to mesh vertices).

You could use the Integrate plugin for that (integrate "1").
