You need scrot, xclip, and libnotify. Set up private key ssh access to your webserver and update the directories/url and you're good to go.
To learn Ruby, I wrote a script to make command-line uploads easier. It currently supports S3 (including torrent and authenticated expiring URLs), Cloudapp, and Imgur (for images). You can check it out here:

PS : I know it's not the most portable script it the world, but it works like a charm once installed..
Would be cool if you could change the output location of compiz' "windows key + mouse rectangle produces screen shot" add on.
I use a Dropbox directory to share content between my Linux desktop and my Windows laptop.
