+Use cases for examples:
+    mailserver
+    `bip`
+    OpenSSL in the cloud
+    etherpad
+    openID provider
+    read into OAuth / OAuth2
+    diaspora
+    opensheet

+
+cartridges:
+	Openshift is platform, carts provide framework
+	defined as manifest, set of control scripts, and supporting files to provide one service instance
+	cart manifest is similar to spec file, but in YAML
+	multi-version implies that all versions must be available on the system
+	app upgrades must be seperate from RPM upgrades
+	inter-cart deps, configure order, etc can be an issue
+	carts can *own* the gear
+	cart devs live on GitHub?
+gear:
+	- locked homedir
+	- namespaced mounts (/tmp, /dev/shm)
+	- cgroup restricted
+	- restricted via selinux
+	- port binding is restricted
+
+apps in a gear require:
+     - public facing cart
+     - appropriate dependencies
+     - code/config to determine appropriate IP/ports (env vars)
+     
+
+
+OpenShift:
+	quickstart
+		- defines an app?
