Unless I missed something, outsourcing watching the blockchain cannot be called trustless; they need to know what to watch. If your watcher collaborates with your LN-hub, you are doomed.
Here is my get-rich-quick-scheme:
* Setup a big LN hub.
* Setup a LN-watching service
Then for each peer connected to both, I filter those that:
* have a balance with <10% on my side
* have an earlier balance with >90% on my side
* haven't been seen for a week.
For those, I submit the tx of the earlier balance. Sometimes I'll lose a bit but mostly I will gain more.
Bitcoin doesn't require weekly check-ins, but Good to know (thanks) - that's a less extreme requirement for Lightning. However, being online wasn't a main pressure for the potential problem of central hubs.
(e.g. the large parked capital requirements acting as a barrier to entry, fees - if bitcoin is to be a low-volume settlement layer - plus people wanting to keep spending money consolidated (i.e. opening as few channels as possible) while still getting the benefit of complete payment connectivity)
