+  AuthServiceProxy has the following improvements over python-jsonrpc's
+  ServiceProxy class:
+
+  - HTTP connections persist for the life of the AuthServiceProxy object
+    (if server supports HTTP/1.1)
+  - sends protocol 'version', per JSON-RPC 1.1
+  - sends proper, incrementing 'id'
+  - sends Basic HTTP authentication headers
+  - parses all JSON numbers that look like floats as Decimal
+  - uses standard Python json lib

+  AuthServiceProxy has the following improvements over python-jsonrpc's
+  ServiceProxy class:
+
+  - HTTP connections persist for the life of the AuthServiceProxy object
+    (if server supports HTTP/1.1)
+  - sends protocol 'version', per JSON-RPC 1.1
+  - sends proper, incrementing 'id'
+  - sends Basic HTTP authentication headers
+  - parses all JSON numbers that look like floats as Decimal
+  - uses standard Python json lib
