To clarify my question a little bit... Net::XMPP does not have controls to configure underlying SSL connection parameters like client certificate/key. The IO:Socket:SSL is still there and I only need a way to get to it via Net::XMPP::Client. When I do data dump on Net::XMPP::Client - theres XML::Stream that should have IO::Socket reference. Is it possible to obtain it while its not being exposed by the Net:XMPP API ?
