Related project: Live CD installer.
Already implemented
When installing a new device with usb live ubuntu, the installation process takes a long time downloading all the updates. On the next installation with the same usb key, this download process is repeated.
Beside, one of the fallback of Linux/Ubuntu is the difficulty to install packages or update computer not connected to internet (I spent times in Africa where the internet connection was an issue). There are solutions (keryx, apt-offline, download script), but far to be straightforward.
