    IMO where LN shines most is when large centralized wallets providers say Bitstamps and Every_Other_Exchange want to allow users to move funds to and from any exchange. there can be LN channels opened connecting all these echanges together, the channels are almost never closed, it is simply a trustless way for all the exchanges to track the movements of user funds back and forth.
    from the user point of view he logs into bitstamps and request XBTC to be moved to MtGox, and in 3 seconds flat his account( or any other account he wants to send funds to ) on Mtgox is credited.
    user doesn't need to worry about operating the channel, the exchanges do that behind the covers.

    if your brain is saying " RED ALERT! " after reading this, congratulations you "get it", but you'll probably still use this killer app yourself... admit it!

    firstly. LN was envisioned due to your exact theory.. a background mechanism for exchanges.. blockstream made a private "liquid" network using multisigs. and then realised it could be used more broadly.. and thus LN concepts came to fruition.

    it must be noted that channels need to be closed because the locktimes expire due to time and utilizing the time to make old 'payments' irrelevant, thus it runs out of time sooner to keep latest relevant and needs to close to secure a most relevant mutually agreed 'payment' before older LN payments become relevant.

    EG imagine now its 02:00:00 26th Nov 2016 that the 'deposit' is paid.
    with a locktime of say 03:01:00 26th Nov 2016 (1h1m) for simple explanation
    first payment in LN you set and agreed to make it more relevant but unspendable until 03:00:59
    next payment in LN you set and agreed to make it more relevant but unspendable until 03:00:58
    next payment in LN you set and agreed to make it more relevant but unspendable until 03:00:57
    and so on

    obviously it doesnt mean you can do 3660 transactions(1h1m).
    because:
    you may not transact for 10 minutes. meaning you missed out on 600 possible alterations to the locks by doing nothing.
    EG time is 02:10:00 - you cant write a tx locked to be unspendable until 02:00:01 because that time has passed.
    you can only alter the locks while available locktimes exist ahead of realtime meaning doing nothing for 10 minutes leaves you only 3060 possible tx's

    you may not transact for 40 minutes. meaning you missed out on 2400 possible alterations to the locks by doing nothing.
    EG time is 02:40:00 - you cant write a tx locked to be unspendable until 02:00:01 because that time has passed.
    you can only alter the locks while available locktimes exist ahead of realtime meaning doing nothing for 40 minutes leaves you only 1260 possible tx's

    also because
    if you opened the channel at 02:00:00 and instantly done 3659 tx's in milliseconds. the altered locktimes have now got to 02:00:01. so you have to close the channel to broadcast that most relevant 02:00:01 tx before older transactions become relevant/spendable
