Shareaza

IPv6 tunnel when you don't have possibility to open ports and don't have uPnP gives big speed boost to torrent downloading

But unfortunately not many people have an ipv6 connection so their are less peers. But its better than nothing at least.

I think sooner or later Shareaza must and will add IPv6 support, which will make such things more easy with Shareaza...

My provider is switching over to IPv6, they offer both kinds right now, and I guess will move solely to IPv6 next year. When will Shareaza support this is the question we should be asking?
