Using DPoS is a very interesting idea for Shift. Would it be possible to also measure the quality of each delegates internet connection? Seeing as Shift will need peers that have high speed internet for phantom, ensuring the delegates also have really quick internet seems it would greatly bolster the network.
After some time there will be two different nodes on the network, delegate nodes to create blocks and phantom nodes to seed content. The network won't purely rely on delegates to act as servers.
We definitely need to rethink some parts of our economic concept with the dpos switch but at the same time it opens possibilities that were previously harder to achieve.
