Wagneers (who aren't necessarily developers) need simple, straightforward tools to share their creations. In other words, we want to support open-source development patterns for non-developers.
In that vein, there will be a need for github-like functions (if not github itself).
It may often be possible to generate hands dynamically, following structural references, but wagneers will often want to draw custom boundaries around what constitutes a wapplet.
