We've been talking about a set of features around this general idea for a long time, loosely referring to them collectively as "next-gen sync". While Firefox Sync is the technological infrastructure we're planning to use to support these features, that name does not encompass the full vision of what we have in mind. For this reason, we feel that "Firefox Cloud" is a more appropriate project name at this time.
