                    create <u>remote</u> clients like FLASH5+, APPLETS or anything 
                    that could &quot;speak&quot; XML. Thanks to the XMLConnector 
                    service you can also create <u>XSL</u> skins, so plugged to 
                    an XSLT processor you can transform chatroom's content into 
                    documents viewable for many devices (PC, Mobile, PDA ...).
