Process substitution is a bash-ism. Just looking at this snippet I would
ask why you aren't just using stdout, but from the whole diff it looks
like you're using --write-out and want to keep the streams separate.

The POSIX shell way would be to make your own named pipe rather than
anonymous one:

  mkfifo data
  sed ... <data &
  curl ... --output data
  rm data

But I don't think relying on bash is that big a deal, as long as the
script is clearly marked with the correct #!-line (which it is).

The ">cat" isn't doing AFAICT, though.
