I just sent off my RPi for colocation in a data center. I'm going to write a few blog posts about my experience and hopefully, it's gonna be an AWESOME one
Feel free to visit my totally non-commercial blog (which is going to be moved to the RPi later on) here: http://trick77.com/2012/07/02/colocating-a-raspberry-pi-debian-server-in-a-data-center/
