As you know, RCP had a number of docking framework integrations. However none of the frameworks currently supported are active. Which begs the question, should they be included in Valkyrie?
As far as I see, there are currently 2 good options: MyDoggy (opensource, free) and Jide Docking (closed source, paid). If I'm not mistaken, the MyDoggy integration was already done by Peter Karich, so there's just some integration work there.
