The truth is, this whole thing is a bit of a hack (or maybe a heuristic); I really should be looking at the value of g2_view, rather than the URL Rewrite of tag/. I don't have my G2 install around anymore, and I'm not 100% what the correct URL would be in any case.

That said, you are correct about the goal.

Does the snippet above support tag_albums' override of the tag controller? The new controller at "tag_name"  does.
