Interesting idea.
A limitation of the temporal addressing is that variables live on entry to a basic block have to be put in the same position on the belt on each path which could enter the block. This is okay for loops, but it's going to require lots of shuffling about in conditional code. Still could be worth it, of course.
They will probably do lots of if conversions to avoid this and to make use of the 33 issue slots. They could also add special instructions to push several values on the belt to keep different paths aligned.
