thanks,
I am probably hoping for too much(?) - without man made 
constraints but sort of cluster logic would make these 
decisions: wherever it decided to start/run resourceA then 
rourceB would have to run on different(all or remaining 
cluster's nodes).

I'd only have to tell it something like: if you started 
resourceA on nodeA then remaing(or maybe specific) resources 
start on all but nodeA nodes.
