So the idea is that if you never receive on a channel then you don't need a watchtower, right?
Could this be used without internet access but having network connection to the recipient (assuming the recipient is the other end of the channel of course)?
Yeah, right, you don't need a watchtower while being offline.

That's the general idea, but we need to examine this further, whether there are some issues with that.
