Best way to use Unix domain socket in bash script

Question

I'm working on a simple bash script daemon that uses Unix domain sockets. I have a loop like this:

#!/bin/bash
while true
do
    rm /var/run/mysock.sock
    command=`nc -Ul /var/run/mysock.sock`
    echo $command > /tmp/command
done

I'm echoing the command out to /tmp/command just for debugging purposes.

Is this the best way to do this?

Looks like I'm late to the party. Anyway, here is my suggestion I employ successfully for one-shot messages with response:

INPUT=$(mktemp -u)
mkfifo -m 600 "$INPUT"
OUTPUT=$(mktemp -u)
mkfifo -m 600 "$OUTPUT"

(cat "$INPUT" | nc -U "$SKT_PATH" > "$OUTPUT") &
NCPID=$!

exec 4>"$INPUT"
exec 5<"$OUTPUT"

echo "$POST_LINE" >&4
read -u 5 -r RESPONSE;
echo "Response: '$RESPONSE'"

Here I use two FIFOs to talk to nc (1) and fetch it's response.
