+    - Change the way we get local host's domain name on UNIX:
+        instead of gethostbyname()
+        (which has nightmarish linkage problems that no one quite understands)
+        use "ping", which we assume exists on all UNIX systems,
+        and parse its output
+    - Allow Python scripts to access remote databases
