I saw these two repositories through the -wizards IRC channel earlier
today. I have not reviewed any of the source code for quality, security or
functionality, so I don't have word to offer regarding status of these.

https://github.com/LightningNetwork/lnd
https://github.com/LightningNetwork/lightning-onion

Also other git repositories with related work:
https://github.com/ElementsProject/lightning
https://github.com/matsjj/thundernetwork
