Just like our current inventories contain meta-inventories "Library" (Standard Linden-Supplied objects and "My inventory", It should also be able to contain meta-inventories of group-owned objects. I am trying to become involved in collaborative projects, such as builds, scripting and machinma and this would be very useful to pass around Frequently used objects, or introduction kits to groups. This is also enourmously useful if a group member who had something you wanted has gone off line - you could just get it from your collective library.
Other possibilities:
-This group inventory could be wiki-like. It could be set so that any group member could modify or create any object in the meta-library
- You could also set permissions e.g. only group officers can modify or create, but all group members can view or copy from.
Etcetera! Please implement this in the next version of SL! It can't be that hard!
