One thing, an idea drawn from the solsylva design and adapted, instead of the metal flat, why not run your rail edges on a router table to create a groove for each piece of metal, and use square tubing recessed in the grooves.
This will give the same effect as the flat bar, but you can then drill and thread the inside edge of the tubing to take bolts. The tubing can be bolted in from the opposite sides with the bolt head's recessed into the wood also. This would also work with solid square bar, or thick enough flat.
Again, great idea. Simple, easy to build, I imagine very ridgid with some alterations, and could be very inexpensive. I like it! :D.
