This is for a small project of limited edition audio or pictures or
scripts, etc.
Hens, "I'd like" to limit each user in the allotted 150 to be able to
download (whatever it is) only once.
But up to 150 users can get in on it kind of thing.

Yes the users will have gone through a registration and login to
get to the downloads.
The files will be served from MySQL and output to HTML of Flash.

While DB logging is definitely the way to do it, I would suggest
not to rely
on ip logging as authentication mechanism for following reasons:
Most end-users are on a dynamic IP.
One IP can/will serve multiple users (any large institution with
wireless
(Universities, Hospitals etc.) will have hundreds or thousands of
people
surfing with one public IP - which is the IP you're logging)
Is there any reason not to log them in by personalized means?
(such as
email/username)

For that you would probably need to setup a databased system in
which
(best scenario) they would need to register prior to downloading or
(not so secure) capture their IP address and prevent that IP from
downloading it again (example below).
Since you are already using the php script to detect the
download, you
could simply add (assuming MySQL) a Mysql query such as:
$result = mysql_query('select dt.downloads, ip.ip_address from
downloads_table dt RIGHT JOIN downloads_ip ip ON ip.track_id = "%
your
track id%" AND ip.ip_address = "'.$_SERVER ['REMOTE_ADDRESS'].'"
where
dt.track_id = "%your track id%"'); $results =
mysql_fetch_array($result);
if(($results['downloads'] <= 150) && (empty($results
['ip_address']))) {
mysql_query('INSERT INTO downloads_ip (track_id,ip_address) VALUES
("%track_id%","'.$_SERVER['REMOTE_ADDRESS'].'")'); // insert IP into
downloads_ip table mysql_query('UPDATE downloads_table SET
downloads =
downloads + 1 WHERE track_id = "%track_id%" LIMIT 1'); // update the
count of the downloads // do download here
} elseif (!empty($results['ip_address'])) { echo 'you have already
downloaded this track...';
} else {
echo 'this track is no longer available for download'; }
(note I haven't checked the code, but it should give you a quick
example of how you can keep track of this)
Hope this helps, and if you have any questions just let me know.
Take care,
