 = Analysis =
-^(Give as much as possible of the needed information for designing and implementing the task in the following sections.)^
 
 == Overview ==
-^(Provide a brief overview of the whole task in its first revision. Stick to the current revision of the task, but keep an eye to the whole task progress, and stay alert for possible smells.)^
+
+Remote objects are those that are stored on a server.  A book is a remote object, as is an image.  Sophie needs to be able to handle local and remote objects equally.
+
+Load times are important.  For example, if a timeline is told to play, it needs to know that all objects are usable in some state before the timeline can be started.  Along these lines, if the timeline changes a page and the page is not loaded, the timeline needs to pause until the page is load, or continue in a non-blocked manner.
+
+This is one example of how remote objects need to either report their loading status, or block a semaphore so that other objects can block until the loading is done, OR remote objects need to degrade gracefully if not fully loaded (although I don't see how this can happen)
 
 == Task requirements ==
-^(List the necessary requirements that the task must fulfill.)^
+
+ * Define how remote objects will work in Sophie
+ * Define how different types of remote objects might be loaded (a movie on a website not connected with Sophie)
+ * Define how the loading protocol will work, such that other systems can block until loading is complete
 
 == Task result ==
-^(List the end product of the task (for example "Source code", "Wiki page", etc.))^
+
+The result of this task is code
 
 == Implementation idea ==
-^(Provide some rough implementation idea(s).)^
+
+ * There may be many different ways to load remote objects, but PRO_LIB cannot use it's own extensions system, so there might need to be a new registration API
+ * Remote objects may go through the change server to load, which would also allow for caching
