6.3 WoT servient on Smartphone - Browser + Servient about wot-architecture

[mmccool]

I rewrote these sections and I hope made this clearer. The only difference as far as I can see is that in one case the browser runs on a different device, in the other it runs on the same device. I did rip out some redundancy in the descriptions.

In practice, these are a bit different. In particular, to get remote access to a Servient running on a phone, you would have to convince that phone to run a web server. This is not that easy to do, and we probably should discuss access point modes, etc. Then there's the issue of providing a global URL and DNS entry, pointing back at the phone, etc. etc.

Of course we could just remove one of these two use cases, too.

Running a server on a smartphone is not an issue.

The only problem is how to get the connectivity remotely, which is somewhat comparable to edge hubs behind a firewall. We should rather discuss this in a connectivity section.

Let's solve this as discussed in #24 and see the original issue posted here fixed in #23.
