Ow!  You're running a find operation for each file.

Here's a more efficient script: (Untested...I don't have decent access
to a Linux box at the moment.)

find /dir/to/start/search >/tmp/mytmpindex$$
grep -f file.txt /tmp/mytmpfile > /tmp/mytmpfoundfiles$$

for i in $(cat /tmp/mytmpfoundfiles$$)
do
cp -p ${FILE} /local/dir #copy file from remote dir to local dir
done

rm /tmp/mytmp*$$

...

It would be even better if we could guarantee that the locate db was
up-to-date and would return all relevant results.
