First up, to be honest, I don't plan to use or involve myself with 0install for any activities I'm involved with (may be if it works invisibly as a worst case fallback)... But, if a deployment/teacher wanted to distribute one (or several) of these non-Sugar compliant installs on a USB stick for remote class installation, is it a trivial step for them to put 'the activity' on a stick so it can be installed without any network access or local server at install time?

Example: Teacher travels from a remote village to an education ministry or town with internet access once a month. Downloads a selection of new activities and content from ASLO to their USB stick. Journeys back to their village and uses the USB stick to install/upgrade each machine, kids also share the activity .xo bundle from Journal with friends who can't make it to the school.
