Adobe Releases Cross-Operating System Runtime
"Once the Apollo apps are created, users can launch them from their desktops, without using their browser or connecting online."
Sounds a lot like Microsoft's ClickOnce technology: http://msdn2.microsoft.com/en-us/netframework/aa49 7348.aspx
And Microsoft "auto-updates" Windows machines (whether or not you want them to, it would seem) to include the latest frameworks and such. Regardless, how does what Adobe does improve on what Microsoft (and I'm sure some F/OSS alternatives) already do?
