Development Team/Collaboration Refactoring

Introduction

During the 0.90 release cycle, Collabora is sponsoring the refactoring of the presence and collaboration framework in Sugar with the following objectives:

• reduce the dependency on deprecated or soon to be deprecated parts of the Telepathy spec,

• improve interoperability with other messaging systems,

• make it easier to implement further collaboration features, often developed for other systems.

The strategy that will be followed can be summarized as turning Sugar into a normal Telepathy client.

Instead of implementing these changes inside Sugar's Presence Service, we are going to remove this layer because of the unneeded complexity that it brings and because several of the services it provides are either obsoleted or replaced by new components in the Telepathy framework. See Development Team/Presence Service Removal for details.
