Sharing Scripture Annotations

Is anyone working on the capability to share scriptural annotations with others? For example: I teach seminary full time. When I share a quote from a Church leader that goes along with a particular verse of scripture, I would love the ability to send that quote as an annotation linked to that verse in my students personal electronic scriptures. This would require the ability to set up a group to send annotations to (my seminary classes). It would probably also require the ability for individuals to accept or deny suggested annotations. But wouldn't it be amazing?

It would be great!
There is something like this that can be use instead. I tested it several months ago, but I don't remember its name (I'll check out).
But Google are thinking about this (SideWiki). You can let a comment in a page you visit so other can read it.
If this comment regard a scripture's page it will do what you are looking for, isn't?

Here is a great site where some of this tools are shown.
