It will depend on a couple things. For one, how the rafters are framed makes a big difference. Most have bracing and gussets and can handle the weight, some of the older stuff may not. Second, were in the room do you want it? A door-way is the best in terms of support and would have no problem holding 400 lbs., the middle of the room with no support (from above), might only hold one of you, whereas next to a wall will support more.
All this depends on how hard you plan to play,
When in doubt add more support.
For most people/situations a frame
made for swings works good and can be taken apart for storage (if you have the room), or the door mount models.
Hope this helps at least a little, you could always ask dad if a certain spot would hold one of those chairs that hang from the ceiling. lol
