I think this is top priority. The people with the skills to revive this and modernize BBS client and server software with modern crypto should get working on it ASAP. I shouldn't need to run UNIX or GNU or anything else to send someone in my city an encrypted message, you didn't in the 70s and 80s and you don't now. Someone please make this happen (create the software and hardware platforms) and post detailed instructions on how to set the servers and clients up. Forget GNU, forget Tor, what I'm describing is the actual solution to the problem. Everything else is smoke and mirrors bullshit. It existed in the past it will exist again but this time better and more secure.
Of course international communications is another story and GNU and Tor is the best we have for that right now. But get the dumb machine to interface with SOCKS5 on Ethernet and we're in business (Tor Proxy). I anticipate that there will be an Ethernet module published for the RC 2014 within the next 3 years. There are already Ethernet modules for the Commodore 64 and other units. Forget TAILS, this approach is the answer. A text based HTML 1.0 Client connecting by SOCKS 5 on a dumb 8-bit machine to a Tor Proxy on LAN running on a minimal GNU or OpenBSD server on non X86 hardware. Then specialized Shit posting Text only boards that are onion hosted can be created for posting to. That's pretty much the end of the line.
