Yeah, I'm thinking the same actually. If LN becomes too popular (due to it's instant transfers with virtually 0 fees) then I guess some kind of see-saw mechanish would be ideal. I'm guessing there will always be people out there who refuse to even use LN. Hardcore BTC Maximalists, probably wont use it, but who knows.
It's pretty cool that Stakenet actually made a setup, where the Lightning nodes is incentivized to run through masternodes. It's actually genius, so I wonder how it will pan out in the end, in terms of adoption.
If LN keeps BTC's integrity intact and strengthens it's privacy, going out of the way to use on-chain for every transaction seems a bit much. I guess there will always be some people insistent on using on-chain tx. They'll help secure the network, so that's nice.
I already bought wallet ledger and trezor hardware, if they make their own coins, I will also invest. Besides the benefits of making hardware wallets, they can make their community bigger by making their own coins. Coin making with its own benefits in using hardware wallet products is a good idea, but I think they are more focused on hardware wallet and its development.
In a project there must be a marketing team, I think why the project you are talking about has a low level of interaction, is lack of promotion and advertising. You can use bounty and some social media sites to attract attention.
To be fair, XSN Viper is still in prototyping.
