Liaison statement
Update on LEMONADE activity

The LEMONADE working group (WG) would like to thank the OMA Mobile Email Sub
Working Group for your latest liaison.

We would like to update you on our progress.  Of note is that we have several
RFCs that have recently been approved:

RFC 4467 – IMAP URLAUTH
RFC 4468 – IMAP BURL
RFC 4469 – IMAP CATENATE
RFC 4550 – LEMONADE Profile
RFC 4551 – IMAP CONDSTORE

In addition, we are nearing completion on several of the documents in
discussion in the WG.  The following documents are either in or will be in WG
last call after our meeting:

Draft-vaudreuil-futuredelivery
Draft-ietf-lemonade-convert
Draft-ietf-search-within
Draft-ietf-lemonade-deployments
Draft-daboo-imap-annotatemore
Draft-melnikov-imap-search-res

In the LEMONADE Notifications document (draft-ietf-lemonade-notifications) we
have based notification on OMA EMN.  However, in the development of the
functionality we have the need to identify items (such as message subject,
date, sender, etc.) that are not part of the EMN mechanism.  As a result, we
have described these as a different extended notification payload in addition
to the base EMN payload.  We request that OMA MEM examine this extension and
indicate if our current approach is suitable and if OMA would consider
extending EMN with these capabilities.

As we have indicated before, the LEMONADE WG is working on a set of extensions
to IMAP and ESMTP to support mobile email.  This set will be succinctly
described in the LEMONADE profile (draft-ietf-lemonade-profile-bis).  We
understand that the OMA TS will normatively reference the LEMONADE profile for
the MEM protocol.  In order to help us understand your usage better, we would
appreciate a presentation on the OMA MEM TS for LEMONADE.

Finally, LEMONADE is considering options for an interoperability event. 
interop.  From an IETF perspective, our interest is only to facilitate protocol
maturity.  Specifically, that is to prove the feasibility of the protocol and
to document multiple interworking implementations.  We are discussing a private
event in Fall 2006 to initiate this testing.  Our results could be input to OMA
MEM for use in your interop events.  And also this could be followed by
marketing/interop at Telecom 2006 and 3GSM trade shows.  Would OMA MEM be
interested in interop events?
