This was actually the hint I needed, and I now have it working, I used:
  >&$1 printf 'your file will be ...' ($1 is the parameter %h)
and ended it with
  exec >&-

Now I just need to re-verify my permissions are safe by uploading/downloading arbitrary php files, then get it working with batch downloads. I'll share it with everybody then if there's interest.

Then I'll go rewrite it in JavaScript. My JS is rusty, but porting this over should be a good way to jump back into it.
