Understand what it is and how it works (in theory). I'm wondering how do I physically utilize those nodes in that picture to my advantage right now?
I believe it can be done via scripting only for now, and ONLY on testnet. The ability of fast "direct" transactions and minimum fees is something everybody wants and fast. AFAIK, (haven't been following this to be honest) there's no release date yet. But, from an article I've read the LN needs to be thoroughly tested prior release (any different input is greatly appreciated). At these prices the problem of having a bug and release it out in the open is not recommended...
PS: Yes, I'm back... (kinda)
