To access cloud datastore, you need either service account credentials or u must have access token for authenticated user with Scopes set to Datastore, and user email.

Use Google api Client library,or simply use ProtoBuf library provided in documentation.

Answer 2

Your questions:

1) No, cloud datastore can also be user by other platforms

2) App engine has native support to use the (cloud) datastore. The cloud datastore is based on the App Engine datastore to make it available for others.

3) You can share the cloud datastore, but see this issue
