No. hook_nodeapi works on the new node "version" (new data). I need the 
old value and the new value.
The work is simple: get "foo" field value from node A via 
"nodereference" field, subtract 'bar' field from "old node" and add 
'bar' field from "new node" , save the node A with the new value of the 
"foo" field.

Sorry for my bad english.
