The #WASM support seems neat. I heard somewhere that there's a way to perform a query on multiple DB backends at once, so it'd be cool to see if that's possible here.

With that in place you could query data from multiple peers together without needing to merge their datasets.
This is kinda the approach I took for HyperBeeDeeBee in applications where multi-author queries were important.
