My preference would be Dverse (for the user-facing dApp). It’s got the association to ‘decentralised’ and suggests a ‘dApp’ universe (or federated dApp as I take your vision to be). Although I’m not enamoured by Klick, I see your points regarding its accessibility (especially to the Asian market). For me e-Klick would align it more with etonomy (but still wouldn’t beat Dverse). Droot made me think of droop/droopy/flacid. Flout made no impression either way - a bit of a non-impact name for me.
