There are however couple of issues to think about in situation where the system is automatically accepting packages from the other machines in the network.
- how to make sure that the system is able to save all packages advertized.
(for example what happens if new packages will require 150 mb in size even without extracting them and one has only left about 100 mb)
- how to prevent someone to make malicious local laptop which advertizes some bad applications for other local OLPC laptops. Should every single chunk of the apps be signed, if yes, then the verification of those chunks will also require some cpu...
- some kind of cleaner is needed to make sure that old "uploads" are removed from wasting space, once there is already newer version coming or installed.
(situation where you have received 30 % from glib 2.18.14 when that is updated again to something like glib 2.18.15)

I know those are all doable, but making them 100 % bullet proof is not easy task.
