Carbon Copy: works (meesages go to Psi+ and Conversations) Mentions: work (notifications when my nick is mentioned in a conference quiet otherwise) Notifications on keywords in a conference: not implemented (oh well). Overall it's not as feature-rich as Xabber but so far it's less buggy and the UI is much better."
