+ * will not load on systems without those libraries ... but that's harmless.
+ *
+ * Currently the only daemon we communicate with is NetworkManager. We listen
+ * for NetworkManager state changes; we set nsIOService's offline status to
+ * FALSE when NetworkManager reports NM_STATE_CONNECTED, and to TRUE otherwise.
+ * We also solicit the current status from NetworkManager when this component
+ * gets loaded. In addition to setting IOService, we also set the
+ * "browser.offline" preference (because Firefox treats that preference as
+ * authoritative). We have to wait until prefs have been loaded before setting
+ * "browser.offline".
+ *
+ * In the future we could extend this class to talk to other daemons.
+ *
+ * Currently all communication is asynchronous. This isn't hard to implement
+ * and avoids blocking our main thread.
