still: 'Making your own ipfs service' example does not work

This is a followup of #2401:
The example still doesn't work although it's part of the official documentation:
https://ipfs.io/docs/examples/example-viewer/example#../api/service/readme.md

Might be that #2401 has rightfully closed at some point in time but the corenet --> p2p change broke it (again).
Could it be that this example is somehow obsolete anyway? In the meantime there is https://github.com/libp2p/go-libp2p and maybe that's a better starting-point?

In that case i'd suggest to remove the example.
