There is an idea I have entertained, but have been too busy to try much of it.  Certain nodes will chew through liquidity like water... WOS for example.  So I can open a king sized channel... set fees to whatever will more than cover the two tx fees.  And then close with a profit, rinse lather, repeat.

But that feels dirty.  Not because of fees, but because of settling on the main chain over and over.  Defeats the purpose somewhat.  I think the protpcpl is where the channel balancing problems may be best addressed...  but I am not sure exactly how.  There is no reason though that we should not be able to see channels be drained and filled over and over.  Still thinking about it.
