As Carl and Hans suggest, I believe Views can do handle double tiered relationships, although I think it's easier in Views 3, which is probably not a full release yet, but quite stable for all that I've done with it. But I think you're looking for back references, and I'm not sure what modules can handle that.

From: "Hummel, Tracey S - (thummel)"I have a Drupal 6 site that has content types/node references that look like this:

Keyterm àConcept à Standard

The content type Keyterm has a node reference to Concept; the Concept content type has a node reference to Standard.

On each Standards page, I want a block that lists all Keyterms associated with the Standard (related through the Concept). Any thoughts on how this could be done or example sites?
