Look at glorious failures of the past attempts to go "cloud." Danger put your stuff in danger recently -> http://www.precentral.net/living-cloud-dangerous-just-ask-sidekick-owner
And look at the old "thin client" attempts.

My thought is to let others risk their businesses on the cloud. We'll stay old school and new school. That is we'll use both!
Slingplayer servers have been up/down for several days now. Multiple threads in their forums complain that logging on and off the application is hit and miss. Apparently the software needs to log on every time you start it....Can you say "single point of failure"
No real explanation from Slingplayer on what is going on.
