I just tested this and it does work.  If you want to try it yourself, do
this:

from terminal one
-------------
touch testfile
vi testfile


from terminal two
-------------
tail -f testfile | grep OK


from terminal one
-------------
type something in vi.  Every time you save the file, you will see any lines
with OK in them.
