Automatically Updating your Applications (Not NoTouch!)

[Administrator]

I like how some applications can background download yet more importantly, on startup of the app, either automatically, or via user prompt, update itself, then relaunch after the update is complete. I've studied this from using an application launcher that checks for downloaded updates, handles the installation, then launches the main application, to other methods. I'm curious what YOU or YOUR COMPANY are using to handle this type of method. I'm not talking NoTouch as we know this is very limited, I'm not talking about ClickOnce as it's not here yet! What are your "patterns and practices" (non-BITS) for automatically updating your distributed applications? (Winforms)
