Do you want to list all relation nodes between any objects of type A? I assume that B

I suppose you have to list all object of type A and then count all related A nodes
iteratively.

??!!?? Why would this be any different then cloud.getNodeManager("A")?

Perhaps something like <mm:relatednodes path="A,related,A" element="related">, or the
Bridge
equivalent of that.
