With Memcache one can not build a BTree, for instance. There is certainly a merit in Inderjeet's suggestion. If there is an API through which we can restrict GAE to a single instance, a lot of new applications/services can be thought of. A document database, on top of GAE with all indexing in-memory data structures, is one example immediately coming to my mind.
