Creating Uploader/Searcher with groups filter capabilities

Hi,

We are testing the moodle-plugin and we miss the feature to allow an user to upload/search only on a specific group.

We would like to know if it could be posible to implement or not.

We saw similar features on some plugins like Elgg and BudyPress. But we are not currently sure if our feature could be implemented by creating a new Widget via KCW.

I hope somebody could give some more information.

Many thanks in advance
