[development] Node reference in core?

Organic Group?

We deal with a similar issue with community media.  Producers have a
Project/Series which contains multiple Shows/Episodes.  Most stations
organic groups to associate the Shows to the Project... which has the
added bonus of allowing multiple users permission to update the
Project as well as provide the relation for other content types as
well (like the taxonomy suggestion).

We require users to submit Shows individually because there is a lot
of additional metadata for the Show.  To save time, we included an
option in cm_project to set the Project's value as the default for any
field shared between the two types.

Seems like if would be easy enough to add form fields to add X number
of track nodes when the Album node is created using the OG to
establish the relation.
