The Lemonade Profile is a set of protocols and mandatory extensions which provides email access to diverse environments, including mobile handsets and other resource constrained devices.
This allows the protocols to continue to leverage the vast body of work on SMTP, and also means that any traditional IMAP client can interoperate fully with a Lemonade service.
Lemonade does not intend to provide only for PDAs and smartphones, but to include laptops on trains and planes, e-mail access over satellite links, and other environments with constraints on bandwidth, latency, and client memory.
The discussion during the formation of the group became entrenched in finding a name which encompassed all these environments, leading to a comment from the chair, "We may as well call it Pink Lemonade and have done with it."
The discussion moved on to more technical issues, but the name remained, although a backronym was formed as "License to Enhance Message Oriented Network Access for Diverse Environments".
