@cmthiede @zleap @gimulnautti @davetroy You mean firewalls? There's ways around that by making it look like HTTP traffic I think.
But yeah. Once you are in a locked down area it's going to be hard to get unlocked. That's why it's kinda something with some urgency to get people using so the economic impact of such censorship would make them not want to do it...so everyone.
That failing, journalists use it for dead drops and stuff and they have some designs published.
