Multiple Value CCK Field as Context Relationship

Hi.

On a panels_page, I'm trying to pass the values of a Nodereference CCK field with multiple values to a panel_view, using a Relationship in the context system.

The nodereference relationship only seems to support passing the first value to the view. Looking at other relationships (term_from_node, user_from_node, etc) they all seem to pass only one object.

I'm surprised that I've been unable to find a plugin that supports passing multiple values. I'd be pleased to write one, but I'm wondering if I've not found a plugin because I'm missing some larger limitation of the context system.

From what I gather, I'd have to write a new context plugin (say, 'nodes' instead of just 'node') and write a relationship to handle this.

I'd then have to figure out a way to get views to receive multiple nids, which means either
1) serializing the nids and writing a views argument to accept, unserialize and them
OR
2) writing a panels content plugin to manage the passing of data from my panel to my view

or perhaps something else.

Am I way off-base here? Any advice or guidance would be very much appreciated.
