#pubky is starting to blow my mind.  It has one slight weakness, that could be turned into a huge strength.  And that is that you have to republish your DNS every 4 hours.  But anyone can publish it for you.  So a market could emerge to publish the record.  Anything that is an always on server could earn some side income for a simple request, they could do it on repeat for a month.  You would end up paying a fraction of an msat.  We will move to micro satoshis.  But you can even submit this on a phone.  So any mobile anywhere in the world can earn some side income.  The scope and scale of this is incredible, we will be competing for micro satoshis with bots and billions of phones in a competitive market.  It may even turn into a game.
