I suspect there is some amount of confusion here on terms.

The hub is essentially swapping funds between payment channels.

The hub's entire business is centered around having payment channels open with other hubs/users.

If the hub requires user funds to open these channels... then the users have no reason to pay the hub anything in fees.

A hub that doesn't use it's own funds to open payment channels to other hubs/merchants is useless.

That's a chuckle.

As I said, nothing requires the hub to advance anything, and if it does, Bob can expect to pay for it.

We'll see whether hubs assess a fee for depositing funds, whether the fee depends on the amount deposited, and whether it depends on the amount of time it stays there.

I predict "all of the above." There is a name for these kinds of fees. Can you guess it?
