Lemonade was brought to my attention for the guy I'm doing work for. It's a set of IMAP extensions that make IMAP more suitable for mobile phones and devices. Some of their goals obviously overlap with the work the XMPP/Jabber community has been doing. The most obvious being the extensions to handle streaming multimedia content. Looking through their list of goals in their charter, practically every item seems to be handled one of our RFCs or XEPs already. Perhaps its time for the IETF's left hand to check up on its right hand.
