Im working with very similar conditions in my room, but once im able (broken heel) to do so im setting it up to hang. My idea was to space the load across a number of ceiling joists with a single 2x4. it will be screwed in with 3" deck screws to each stud. ill then about 10ft (drawing says 12, sorry ) apart sink t-nuts into the 2x4 to attached 3/8' eye bolts two. they will then connect to a 1.5" diameter galv conduit with 3/8" eye bolts put through with washers. these will transfer the dynamic load to a vertical load. ill then larks head continuous amsteel loops to hammock and loop them around either end of conduit. I saw a similar picture of one somewhere around here but with a 2x4 as the spreader.
illustration to illustrate my take on this:
and obviously not to scale
