I do. I have it installed on Computer Help Forums although I haven't been able to finish the import scripts so I can import my old downloads from Links and Downloads manager the system I used with vbulletin.

 

Just like the other official addons that you can buy it does what it's designed for and does it well. I was able to add a large VM by ftp to get around my 32M php upload limit.

There was a downloads mod on IPB 2.3 which was independent from the IP.Downloads mod, and I used to use that. Did the same thing, really.
