Both the datastore and the app engine servers are distributed systems, so you're not going to have any guarantee that 2 app engine requests are served from machines that are anywhere near each other, nor that any 2 bits of data for your application are stored on machines near each other.
Personally I can't believe that a web request to a server that has to do a datastore request and then return the data it retrieves could ever be as fast as a single process doing the datastore request, but maybe the people suggesting it could be know about some kind of black magic in Google's servers. Not that this means I think that giving apps access to other apps' datastores is a good idea; if they need to use the same data they should probably be 2 parts of the same application IMO.
