Nice work! But I have a real question about Sensei What is the advantage of Sensei compared to a custodial projects like lnbits or lndhub? Since Sensei host the user nodes, it's custodial, so why I would run sensei, pay to open channels on every client nodes (or client paying to open channels) when with lnbits I can manage only 1 node and all users can use my channels? I think I don't get use-cases for Sensei yet. Thanks!
It's a great question. With custodial Sensei and use-cases like you describe lnbits/lndhub are probably better solutions.
We are working on integrating with the VLS (validated lightning signer) project to enable remote signing for all of the nodes run on a sensei instance. Once this lands you'll be able to spin up your own personal blockstream greenlight alternative running entirely from your own instance instead of relying on blockstream's servers.
There are likely some other use cases, maybe in gaming, where you (as the game developer) don't want to deal with the regulations that come into play when you are custody'ing bitcoin and so sensei w/ remote signing might be a good solution.
Even without the remote signing, there might be some research-y use-cases around simulation/testing different network topologies where you want to simulate and control thousands of nodes easily.

VLS is an awesome news, it can provide a bunch of new use cases in the future Thank you for this answer
