You will not need any LNbits account anymore. You will be able to create LN accounts from your own embedded Zeus node, for family and friends. As like in LNbits but this time you could offer your embedded node liquidity to others and they can use it in their Zeus.
ofc you will need to put your Zeus "bank" in persistent mode to keep the LND service alive. But with a nice tablet at home, setup a main Zeus with liquidity, you will be able to run several Zeus around connected to that one. Privately.
