Enable XMPP socket connections This allows chat clients to connect to the chat service using XMPP.
Enable XMPP BOSH connections This allows chat clients to use the BOSH protocol to connect to the chat service. This protocol is mainly used by web based chat clients or ones on mobile devices.
Enable SOCKS5 / bytestream proxy

This provides a faster and more compatible way of file transfer between chat clients. It supports file transfer using bytestreams and can also act as a intermediary between clients that do no have a common transfer method. This allows you to send files between chat clients that could otherwise not send files.
