Thanks for the explanations.

One question: in what order is the text inside the \R{} written--in 
the logical or in visual order?

Why not do what UAX#9 says, i.e. look at the first strong directional 
character in each paragraph?

What do they do, and why is that a problem?

Reversing a buffer (or any part thereof) is a trivial exercise in Lisp.  
But I think what you want is reversed display, not one-time reversal.  
For that, I don't think an Emacs solution exists.  I'm working on that, 
but it will take time.  You can find the details in the archives of this 
list.
