I searched through web site and find an article teaching diy chat function in Kentico. http://devnet.kentico.com/Blogs/Martin-Hejtmanek/June-2010/DIT--How-to-make-a-chat-module.aspx However, this is for authenticated users. I want to integrated chat function also for anonymous users, just like you visit any e-commercial website, they provide online assistance to any customer. Is there an existing web part in Kentico providing the similar function?
