  done this a long time ago. :)

+# Testing the current ZEO implementation is rather hard due to the
+# architecture, which mixes concerns, especially between application
+# and networking.  Still, it's not as bad as it could be.
+
+# The 2 most important classes in the architecture are ZEOStorage and
+# StorageServer. A ZEOStorage is created for each client connection.
+# The StorageServer maintains data shared or needed for coordination
+# among clients.
+
+# The other important part of the architecture is connections.
+# Connections are used by ZEOStorages to send messages or return data
+# to clients.
+
+# Here, we'll try to provide some testing infrastructure to isolate
+# servers from the network.
