BulletMeshStrider

Anyone knows how we can use this? It's on the wiki but it's not explained how it's supposed to be used.

Very interesting find.

It's a btMeshStrider interface wrapper for an Ogre Mesh object. From the API docs you can use a btMeshStrider as a collision volume. This is useful if your geometry is too complicated for the primative shapes.

I have no idea how well it works on animated objects, though I suspect the answer is "not at all" when it comes to hardware skinning.

It's for sharing vertices between graphics and physics. It doesn't work for animations at all, since Bullet has an AABB-hierarchy structure for mesh objects (for efficient collision detection) - you'd have to rebuild it every frame. So it's for static geometry.
