A quick outline:
when a user purchases something, enter an unique string (try
md5(microtime()) although it's not completely unique) into the
database.
make a script that verifies the string...
verify.php?unique=12345............&user=johndoe
in verify.php you'd have something that compares $_GET['unique'] to
the database value, same with $_GET['user']
Then if that's good, send the download link. However, I would use
headers for downloads. By doing this you can place your template files
outside your web directory, which will make it more secure, obviously.
if you know how to use pear then i suggest using http_download. if you
don't, have a look at the fpassthru bit in the manual.

hth... it was a bit too simple but you have the general idea now :D
