Okay, so I've been gone a while.
The home automation project is temporarily on hold, becuase yours truly got unemployed, and can't afford even the cheap hardware required for that project. As the weeks have dragged on with no income, I got bored...
So, I decided to start mucking about with Perl. Why? Well, 'cause I can! It's free (If you have Linux, it's probably already installed on your machine, just do a "whereis perl" at the command line, and you'll get the path to Perl. Then do a "perl -v" and you'll get the version you have installed.)
