rewrite your module , and feed back

firstly , it's a greate module
and thx for you codes , bencode and bdecode , i just borrow them.
i rewrite a tracker base on your code and use drupal as a content management.
a small advice, if you want to upgrade this module , you should pay attention to performance:
using .htaccess+php(just two or three line) to point to a static peers file as a announce , so if event=="" or a fail/error request, it will not query mysql or any php
then , just write down all event!="" to a ".txt" file , and add them to DB on a specific time ,but not do it right on the request come.

while still using your module on testing , mysql will sometimes out of response.if test torrents will go up to 1000 .
and the other one is announce.php , everytime visit this page , seems that it load drupal modules, this will add a little bit confus too

i don't know how to wirte a standard drupal module , so , i just wirte some derty code/pages and using some drupal api
