I have a node setup on a VPS. I could open it up to public use. Any reason to do that at this point? Does this project have enough use to need more nodes for the light wallets?
Additional node is always welcomed. If you set fee address lite wallets will pay small fee but I doubt it will be economically sustainable, most of the owners do this to support the network, not to earn at this point. We will try to make nodes profitable providing them more rewards in the future.
