it's a limitation of a centralized system, which the conventional antivirus or antimalware applications always seem to be. the limitation is on information processing, and also who is to do all of the intellectual labor (can't just automate that, yet...) to find the 0days and upload heuristics and code to remove the 0days, etc.

all of our technology digitally is basically broken, and we are just constantly discovering new ways in which it is broken. As far as the military-sponsored, north american internet project, i think it may be better to simply create new networks that use different software but somehow recycle the existing hardware. This will require extensive reverse engineering, which will only be possible if insiders in the computing hardware industry (especially mobiles) leak code and secrets which keep the technology ossified and proprietary.

Imagine, you can flash the modem and bootloader and everything on your cell phone, and actually have a modicum of privacy or security without sacrificing the use-value of the phone. More than that, it could run background operations (consensually) to run the mesh network. Tying use of the network to facilitating traffic, ala freenet and i2p (but not tor, which is pretty clearly divided between users and servers/hops) etc, will be key. Also, using the internet as a fallback will be necessary to grow the mesh to sufficient size and reliability across geography.

This sort of project is counter-infrastructural, as it reappropriates capitalist technology for a different purpose; the free sharing of information and social connectivity, for the benefit and safety of all
