Proposal: Master-detail capabilities for CCK

The current edition of CCK only allows users to select or unselect node references (i.e. detail nodes) that already exist. It would go a long way to user-friendliness to allow detail nodes to be created, edited and deleted from the edit form of the master node. The ability to do this in AHAH/AJAX would be fantastic.

For example, a node representing a conference. The conference has a list of attendees (typically a list of all possible attendees with checkboxes: very long and user-unfriendly). Along with this list, we require arrival times and flight numbers (call this the "arrival details). At present, we would have to create a Content Type for arrival details, theme the list when viewing the conference node, and edit the arrival details separately.

We should be able to enter the arrival details for any attendee who is marked as Attending, right on the conference form, and either submit changes with the conference form or via AHAH for each arrival detail.
