+ * TODO
+ *
+ * - Completely disable this feature if libsoup support isn't compiled in
+ * - Add "Local Computer"
+ * - Detect machines on local network that runs SSH
+ *   - IP range scan
+ *   - mDNS
+ * - Allow the user to add/remove/edit a machine
+ *   - Use ~/.ssh/hosts as a starting point?
+ *   - Different icons for different machines?
+ *   - Make sure SSH can do port forwarding
+ *   - Make sure the remote host has HardInfo installed, with the correct
+ *     version.
+ * - Allow the user to choose/guess the SSH authentication method
+ *   - Plain old username / password
+ *   - Passwordless RSA keys
+ *   - RSA Keys with passwords
+ * - Make sure SSH can do port forwarding
+ * - Make sure the remote host has HardInfo installed
+ * - Implement XML-RPC server (use libsoup; there's a example with libsoup's sources)
+ *   - Create abstractions for common module operations
+ *   - Use function pointers to choose between local and remote modes
+ *   - Generate a random username/password to be passed to the XML-RPC server; use
+ *     that username/password on the client; this is just to make sure nobody on the
+ *     machine will be allowed to obtain information that might be sensitive. This
+ *     will be passed with base64, so it can be sniffed; this needs root access anyway,
+ *     so not really a problem.
+ * - Determine if we're gonna use GIOChannels or create a communication thread
+ * - Use libsoup XML-RPC support to implement the remote mode
+ * - Introduce a flag on the modules, stating their ability to be used locally/remotely
+ *   (Benchmarks can't be used remotely; Displays won't work remotely [unless we use
+      X forwarding, but that'll be local X11 info anyway]).
