The use of a pop rivet is an interesting idea. But I would remain skeptical until I tried a test on a scrap of thin plywood (as used in an RV). Normally, when using pop rivets with sheet metal or plastic, you use a washer on the back side. The rivets bulge out on the back by the head of the pin as the tool pulls it through. I have to wonder if the rivet bulges much in just the relatively soft plywood (luan). Sounds like it might very well work though for light to medium weight things.
For heavier items like say a table, you need to anchor into something solid like a wall stud or piece of cabinetry (end of kitchen counter, eg.). You can find a stud in a wall by several methods. All of the fasteners in the photo on that website won't work because they are designed for 1/2-5/8" drywall. The toggle bolt would work though and would be an acceptable fastener, but they are going to require a wide hole that won't be easy to patch if you want the fastener off.
Incidentally, I found that if you try and glue something to wood-finished luan and "faux" finished wood (has cheap softwood core) as in cabinets, normal glues don't stick. Seems like the faux finish has some kind of teflon-like coating. Argh. I could not get Velcro to stick to it to save my life, even with adding a glue. Construction adhesive won't stick. Have not tried crazy glue. So, a word of caution, if you try afix a hook or something to this type of plywood, it may *look* okay but it may well fall right off.
