Is that the sound of the tide turning I hear?
No tide is turning, that sound you heard is just flatulence.
Peter R's ideas are an excellent basis for an altcoin. They will have to be put into a BIP and accepted by the economic majority before any tide starts turning.
And until the network experiences actual congestion, rather than simply starting to work the way it's supposed to, you will never have popular support for fixing something that isn't broken.
I'm not sure when you got into Bitcoin, but that paper is an analysis of Bitcoin, without a limit not an idea for an alt? Limiting bitcoin may be what we have now, but removing the limit doesn't make it an alt, to the contrary it'll make it the dominant fork.
I keep having to smile at the people who want to change Bitcoin, they have this unfounded premise that it belongs to them and its a little naive and they say thinks like "you souled try this on a sidechain", or "you should spin-off Bitcoin and see what happens" or "there will be a fork and we'll keep calling cripplecoin Bitcoin and you'll need a new name for the Original Bitcoin digital cash idea".
