If you think I'm here trolling you have the wrong idea - if you bothered to read my LinkedIn profile you'd see that I have worked in mobile/ISP/telco/wireless (since the early 80's). I worked for THUS when the Comms Act was introduced and worked with Legal and Reg on how it impacted the company (and the obligations that it imposed). I do a LOT of mentoring for start-ups (via incubators/accelerators) and get too many LinkedIn requests asking for me to give 'free' help which is why that's on my profile.
I BACKED TTN on Kickstarter and ordered both gateway and nodes.
I realise legislation is different in different countries, but I'm in the UK and putting a gateway on to the 'public' Internet has implications. Postal services in the UK are regulated (by Ofcom too as it happens), yes they are not liable for what they carry, but they have strict rules to the end user about what they're allowed to post.
Electronic Networks are different, but the Comms Act defines an Electronic Communications Network (which could be running a network in say a company) and there are obligations, running a Public ECN has more obligations.
TTN may be a distributed network, but it relies on gateways sitting on an Internet Connection and that potentially has regulatory burdens.
Under the IP Bill for example if you are asked to surrender encryption keys, you can go to jail for not handing them over (until you do). What happens if a gateway owner is asked to hand over encryption keys that have been issued by the network?
I'm sorry if you think I'm trolling, but there are real regulatory issues out there - ignoring them won't make them go away.
