With build 7491 ?

Most of the torrent clients out there are still using the same old BT protocol which is Universal and has been decrypted long time ago. That is why most clients does not work. Your impression about TMnut going after each new torrent client are totally wrong. A company known as Cisco are selling that piece of throttling hardware based on the decrypted code to the ISP worldwide.

Now Utorrent 1.8 Betas, Deluge, Ktorrent (these both are on Linux platform) are using different approach instead of the older coding protocol. That is why it works undoing the throttling.
