I've noticed more activity recently on the LND github page.

Particularily here: https://github.com/lightningnetwork/lnd/tree/master/watchtower 

Watchtowers are coming!

What is a watch tower?

A watch tower watches transactions on the LN for you and checks for counter-party cheat (which reveals a cryptographic secret).  Using this, the watchtower is then able to transmit a punishment transaction and sweep the funds from the cheater into your wallet.  

Of course, your node can be online to watch for this, but a watch tower serves as a backup in case your node is offline for a long time.

Watchtowers are already available for the Lightning Bitcoin Wallet on android.

With this security feature, LN will be even easier and safer to use!
