I love those ideas, especially mesh networking.
SOPA, ACTA, PIPA - it is not a coincidence that governments wanted to pass all this laws after seeing that freedom of speech became real cause of internet and all riots that happened lately.

I would like to see also application that will make sure that your phone is untraceable(i don't have clue about GSM networks so maybe there is a way) and allows you to change IMEI.
Also streaming a data from camera directly to some independent server (one that won't delete content because cops or court is asking to)might be useful for recording violent cops behavior etc.
