You should be able to do both:

1. Use one instance of RoboDK with multiple API connections (multiple instances of robolink). When you use the same instance of RoboDK, item pointers are exactly the same.
   
2. Multiple instances of RoboDK running with one or more API connections each. Make sure you start RoboDK using the -NEWINSTANCE command line option so you open a new instance of RoboDK.
