For a couple of months I've been thinking about a cosmwasm system where there can be namespaces: ability to upload codes to a namespace where they can interact each other but also open permissions to other namespaces you can think of like linux namespaces and a firewall.

First I thought just playing around with a fork but then I think that this could also be achieved if another module had access to hooks like

BeforeInstantiate()
BeforeExecute()
BeforeStore()
BeforeMigrate()

then anx/namespace module can just subscribe to hooks and apply whatever logic.

This is just an idea but not sure if others would find this interesting our useful

Thanks for bringing this topic up. I am happy to see new ideas and use cases rising.
We could replace the keeper instance with an interface in msg_server so that you can play around without the need for a fork for now.

Are intra contract calls routed through msg_server? If so that would help me with exactly what I want

yes, you can find all the message handling in https://github.com/CosmWasm/wasmd/blob/v0.44.0/x/wasm/keeper/handler_plugin.go#L54

The wasm keeper has private functions to not mess with the authorization system but we could provide some adapter here to help you out
