This is pretty great: Some guy called Mobi figured out how to get SMS notifications from his PC once uTorrent has finished a download. He also came up with a way for simple email notifications for all those Blackberry, Android and iPhone users out there. From his tutorial:

"C:/Sendemail/Sendemail -t email@email.com -u test email -m hi, this is just a test email to learn how to use the program. -f fromemail@email.com -s smtp.gmail.com:587 -xu username -xp password"

You know you're gonna love it. Read the complete tutorial here.
