Like mentioned above, you wouldn't want a table attached to the hammock suspension because of the swaying & bouncing.
but then with a razor blade you cut slits through one side wall every third or fourth cell (think plant cell) of the sign so that its flexible. this way it will roll up one direction and will be rigid the other direction. string 2 or 4 zing-it whoopies through holes in all four corners of table and around tree strap for leveling. the sign alone might hold 5 - 10 lbs against the slits before bowing. I might even add some arrow shafts or trail sticks as stringers(perpendicular to the slits) larks head fixed eyes of whoopies for more support as my concern is getting the tree huggers to hold tight enough that it doesnt slide while still maintaining light weight. Im sure there is some sort of tri-glide or double descender ring setup that is escaping me. I think all in all, depending on your need for this sort of contraption, you could build one pretty easily, pretty cheaply that could potentially roll up and pack in that old stake bag from you're unused tent.
