A new IETF working group has been proposed in the Applications Area.
The IESG has not made any determination as yet.
The following description was submitted, and is provided for

Enhancements to Internet email to support diverse service
environments (lemonade)
--------------------------------------------------------------
Current Status: Proposed Working Group
Description of Working Group:
Lemonade is tasked to provide a set of enhancements and profiles of
Internet email submission, transport, and retrieval protocols to
facilitate operation in environments which use Internet-based
technologies but which have link characteristics, device
characteristics, or service environments that are significantly
different from those common on the Internet. A primary goal of this
work is to ensure that those profiles and enhancements continue to
interoperate with the existing Internet email protocols in use on the
Internet, so that these environments and more traditional Internet
users have access to a seamless service.
Lemonade's work is at the crossroads of a body of work related to
Internet messaging, in particular work done by the VPIM, FAX, IMAPEXT
and other IETF working groups. Given the potentially broad scope of
activities this group could engage in, the group will focus
specifically on the following work items:
0. An informational RFC will be produced on LEMONADE requirements.
1. Enhance the existing IMAP4 message retrieval protocol to
satisfy the requirements for streaming playback of multimedia
content.
2. Enhance the exsiting IMAP4 message retrieval protocol to
facilitate its use with devices that have limited capabilities
such as mobile endpoints. The existing standards-track CONNEG
framework will be used if content negotiation capabilities are
needed.
3. Create a message notification protocol for the specific purpose
of servers reporting message status information to other
servers.
4. Create a specification describing the use of Internet message
services in environments where message delivery may take place
using either Internet protocols or through an MMS server using
WAP to communicate with the receiving user agent.
Any protocols defined by this working group will include appopriate
security mechanisms, including authentication, privacy, and access
control. Mandatory-to-implement security mechanisms will be specified as
needed in order to guarantee secure protocol interoperability.
The transport area will be consulted to deal with any transport-related
issues that arise, especially in regards to items 1-4 above.
The working group is aware of several related activities in other groups:
- 3GPP TSG T WG2 SWG3 Messaging <http://www.3gpp.org/TB/T/T2/T2.htm>
- W3C Mulitmodal interaction Activity <http://www.w3.org/2002/mmi/>
- Open Mobile Alliance <http://www.openmobilealliance.org/>
- 3GPP2 TSG-P <http://3gpp2.org/Public_html/P/index.cfm>
- 3GPP2 TSG-N <http://3gpp2.org/Public_html/N/index.cfm>
The goal is to coordinate efforts with at least these groups as required.
While there is obvious synergy, given the end-of-life of the VPIM and FAX
work groups and the similar membership, the working group does not expect
to coordinate with these other groups.
