When all the irc server will support encrypted mode and mIRC too .. Like Https and Http .. Need to do Irc and Ircs .. All the passwords and talk can be sniffed ..
It isn't perfect, and it still does have some problems, but the nice thing is it integrates with mIRC. For example I type /server some.ssl.server 6697 and stuntour auto takes over and connects using SSL rather than a regular connection. It is definately worth a look.
