   - Add a number of public keys to a group.  When the client encrypts to a
     group, use all the keys.
   - Auto-remove expired keys from groups

+More specific stuff

+- Wrap keys in Armor when sending over the wire
+  - Figure out sending multiple keys in the same request.  Wrap in json?  Can
+    Armor handle multiple keys?  Can I just concatinate multiple Armored keys?
+- Auto-generate self-signed certs for testing TLS
+- Password protect private keys?
+  - Where would this password be stored?
+  - Keys would ultimately need to be stored on disk *somewhere*, and they can't
+    be unprotected there.
+- Reorganize code to split client and server and a common lib
+- Look at KMIP.  Do I want to implement this?
