I'm thinking of taking the spare bedroom and hanging a hammock in there. I don't want a stand and don't want to use eyebolts into a single stud. I was thinking of something like this that would be attached in the corners of the room at the proper height and would fasten to at least 4 studs. I'd make it out of aluminum with welded flange supports and an attachment loop for the biner. Any holes in the concept?
