At the heart of Squeak Map3 will be Atom Publishing Protocol (APP)
server. APP is a REST-style protocol that uses the Atom syndication
protocol as the interexchange format between the server and the clients.
Since the list of packages, the list of releases of a package, the
details of a package, etc. will be exposed as Atom feeds, it will be
easy for a client to subscribe to different feeds and to mix packages
from different maps, etc. 
A generic APP server could be easily extracted from the Squeak Map 3
server and adapted for use with Deltas. This would allow the stream
remixing that Goran would like to have.
