What are you talking about? The protocol is standardized, there are 3 implementations in testing, they're sending multi-hop transactions across all 3 different implementations on the Bitcoin mainnest, there's at least one client plus an explorer.
And for the downvoters: I am no shill. I've been holding BTC long-term. I am just a realist with a good understanding of the reliability of software engineers' estimates, esp. in this case.
You can ignore what people say and just look at the evidence, which in this case is pretty clear. Segwit made LN a lot easier, the software is here and working, the fact that they can send a) multihop tx's b) across multiple different clients is a substantial signal about the project's progress. And yeah, don't expect anyone to commit to a more concrete timeline than "in 2018 sometime" when folks like you hold them to it.

It's clearly on track for a 2018 release.
