As far as names are concerned, why not think about how Nintendo formatted their app store's name?
For them, they went with the eShop.
Why not build around that idea?
eShop = electronic Shop, or at least that's the closest they've hinted to.
How about:
bDrop = brew Drop
As a payload must be "dropped" into memory to take over usermode execution, and this "dropped" payload gives us access to homebrew, it seems appropriate.
Not the best suggestion I'm sure, but if we really want it to have a name that's appropriate for the platform, we should think like this.
