Windows (debug): SoulseekQt-2015-3-25-debug.7z
Anonymous in what way? You can already switch usernames very easily and there's no personal information associated with your account.
I think he means to use the soulseek server as a proxy to hide user IPs. Unless the soulseek server has a petabit internet connection, I doubt this idea is possible.
Carl ya that's what I meant, as there is out there p2p programs like that.
If this were possible it would be a wonderful thing.
In the meantime you can think with calm Nir ...
I can suggest to Jbones to try to use StealthNet, downloadable from here: http://www.stealthnet.de/en_index.php
It 'is currently the highest of anonymity in p2p.
Like it was pointed out, there are other networks that provide higher degrees of anonymity. Unless Nir plans to go fully-decentralized and decommission the server, there's nothing he can do to realistically increase the anonymity of clients that you can't already do yourself - by trusting shady third party proxy providers ;)
