Ambient-Oriented Programming

Each Flockr has :

• Profile
• list of its Flocks where it is registered. Note: maybe it should be stored in the profile.
• list of its Flocks.
• * predefined Flocks.
• * user-defined Flocks.

Not sure where to place: list of its friends Flockrs such that the Profile can be consulted offline. When a Flockr is connected for which there is a cached Profile, he should propagate the necessary changed events to make sure that both the cached Profile and the Flocks of the other Flockrs are updated.
