That's really impressive!  This clearly can't be just SQL.  PHP must be involved.

How does one list nodes which have two or more terms associated with
that node? In other words, if a node is tagged as having term 9 and term
33, is it possible to filter upon all nodes which have terms 9 and 33
and then feed them?

Although /taxonomy/term/nn+mm is useful it is only a concatenation method.
    


/taxonomy/term/nn,mm
