This is a Messaging Framework to allow message sending in a channel independent way. It will provide a common API for message composition and sending while allowing plug-ins for multiple messaging methods.

When using this framework, you won't send e-mails to users anymore. You will send them 'messages' and they will decide how they want to get them delivered, that may be by mail, IM, SMS, depending on user's preferences...

Modules using Messaging

Notifications, a complete subscriptions framework which uses Messaging as the sending library. It is also the reference implementation of the full Messaging Framework capabilities.
Messaging Send To, allows forwarding content through different channels (mail, sms, user defined..).

Note that this Messaging framework doesn't provide any visible functions to the user on its own, it just provides messaging services for other modules.
