It surely helped. The following values are the downloads of the Windows version with NotEye integration (until today, not including the adom.de and Dropbox mirrors):

ZIP: 243 downloads (around 14,5 GB)
torrent: 153 downloads

The server only sent about 4 GB through it's own torrent client, but that includes all torrent files (Pre 5, Linux, etc.).

So, yes... we saved a lot of server traffic. I'm not sure if it will be enough for a public release. But we'll see.
