How to use the `discoveryKey` to query values from remote instance?

Nobody has claimed this yet.

Trying to achieve this below scenario, which for some reason is turning out to be complex than is necessary - any help is highly appreciated:

- I have a db setup locally with the following example code
````
const db = hyperdb('./my.db', {valueEncoding: 'utf-8'})
db.put('foo/bar/baz', 'hi')
````
- Now, from the docs it is clear that with `db.discoveryKey` this local data should become accessible remotely
- What is not clear is, how to use this `db.discoveryKey` to query the value of `foo/bar/baz` ?

In other words, I have a `db.discoveryKey` and I have a field `key` - I am just interested in getting the latest value for that field key (and possibly its history, if required), without worrying about keeping the data in sync at the remote.

Is there some API call or some simple way to do this? Setting up replication, sockets, network sync seems to be overkill for such simple task. There must be a simpler way that I seem to be missing.

No files or tests are named in the issue. Start with the discoveryKey documentation and the replication or network API; done means establishing whether direct remote queries are supported and documenting the required usage or clarifying that replication is required.
