A unique address for every device

Sorry that that's the impression. A bit of tech: the sckt agent on the device goes to the sckt server, and asks for a tunnel. It gets an IPv6 address, that is publicly routed, and gets a name (e.g.: storage.acc.sckt.co). Optionally, you can request auth through an HTTP proxy to reach that address, for private deployments. the tunnel to sckt tries to live forever (or until killed), and pretends to be https to get through firewalls.

We have a few hundred Raspberry Pis at our customers' locations, and it's a real pain to keep all the connections up. After a year of hacking on this part of the backend, we might just move to a service like this, if it really delivers on the promises.

From the page, it appears what they'll be offering is basically a VPN tunnel with a routable IPv6 address. Also, it appears that they'll give you some additional control—custom firewall rules, private subnets, etc.

I can see many applications of this. For instance, I could have this set up on my home PBX server and my smartphone to allow me to make calls through the PBX from wherever I have a network connection. I wouldn't have to worry about firewall rules, IP address changes (my home connection gives me dynamic IPs), etc.—everything would just work.

There doesn't appear to be anything revolutionary about this service. There are alternative strategies for accomplishing what I described above: I could have my phone and server connect to a VPN that's set up on a VPS server I lease, or I could set up a dynamic DNS hostname for my home connection, and my phone could connect to that (either via straight SIP or [better] through a VPN). However, those take more work on my part.

Though, the more I look at their (fairly sparse) page and think about what they're offering, perhaps it is just a publicly routable IPv6 address routed over a VPN. Again, nothing revolutionary, but still very convenient.

i have a storage at home on a low-cost arm thingie, if i could easily share my webserver and files with my tablet, that would be awesome. the tablet could run a server to drop files to, too.
