 So Ark? 
 Who is using it? It’s been around over a year right?  
 Nobody, it was announced as a concept last year but I think actual implementations haven’t existed until very recently. There aren’t any user ready versions that I know of.

Your proposed changes just sounded exactly like my understanding of the Ark structure. 
 Ah ok thanks. I need to look into Ark a bit more to understand it. There were some things I didn’t love about it when I heard about it before, such as the ASP taking your funds if you’re not online every few weeks. Granted a custodial LN provider could also take your funds any time, but that would essentially be the end of their business. Assured mutual destruction, so to speak, with custodial LN providers, vs. an ASP basically being pre-authorized to take your funds after what seems like a relatively short period of inactivity.
