Best approach for triangular relations

[heldercervantes]

Hey guys.

I'm looking to implement something a bit more tricky than the usual tags/authors/themes things we usually solve with the page selector.

Imagine 3 sections: projects / news / videos. A item in any of these sections can be related to content from the others. What's bugging me is that there isn't one that's central, and relations should work both ways, so that when a video is added and related to a news item, that news item gets related back. I mean we can be adding a news article and there is already a related video, or we can be adding a video and relate it to a news article (or many). This presents challenges on where to centralise, how to collect relations on the frontend, and even how this is all managed by the admin.

How can we do this and keep some sanity?
