An idea for a way for fluids to travel between a Phys and regular object

[brittle shore]

If you've ever played space engineers you'd know the connector and I think it would work great in clockwork. It would use magnets to align two connectors/whatever you want to call them perfectly against eachother so they could exchange fluids. I think this is the best interpretation for this problem

add #vs-addition message, use hose pulleys or fluid interfaces
