This document is a history capturing the background, motivation and
thinking during the LEMONADE definition and design process.

The LEMONADE Working Group -- Internet email to support diverse
service environments -- is chartered to provide enhancements to
Internet mail to facilitate its use by more diverse clients.  In
particular, by clients on hosts not only operating in environments
with high latency/bandwidth-limited unreliable links but also
constrained to limited resources.  The enhanced mail must be
backwards compatible with existing Internet mail.

The primary motivation for this effort is -- by making Internet mail
protocols richer and more adaptable to varied media and environments
-- to allow mobile handheld devices tetherless access to Internet
mail using only IETF mail protocols.

The requirements for these devices drive a discussion of the possible
protocol enhancements needed to support multimedia messaging on
limited-capability hosts in diverse service environments.  A list of
general principles to guide the design of the enhanced messaging
protocols is documented.  Finally, additional issues of providing seamless
service between enhanced Internet mail and the existing separate
mobile messaging infrastructure are briefly listed.  This memo provides information for the Internet community.

This document is a product of the Enhancements to Internet email to support diverse service environments Working Group of the IETF.
