 - Configurable CA certificate handling
 
 Nice to have:
+- Handle "nochg" responses (f.e. from service dyndns)
+  by outputing a warning to the user that more
+  than one client might be active.
+
 - webcheck mode: Cache last known IP
 
   We only determine the current IP every "webcheck_interval" to prevent server trashing.
