Description
============

This is an experimental module that aims to identify the different
devices (technically clients) that a user uses with their account.

It is expected that at some point this will be backed by a nicer protocol,
but it currently uses a variety of hacky methods to track devices between
sessions.

Usage
=====

``` {.lua}
modules_enabled = {
    -- ...
    "devices",
    -- ...
}
```
