* TODO
*
* - Add hi_deinit() to modules (so they can free up their memory)
* - Import / Export host list
* - Detect machines on local network that runs SSH
* - IP range scan
* - mDNS
* - Allow the user to add/remove/edit a machine
* - Use ~/.ssh/known_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
* - 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
* - 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]).
