Description

Multiplexing has recurred for me a few times now—clients often need to connect to multiple servers simultaneously. Might be worth building something for it into the client SDK.

I think it's not too hard (send all list commands to all servers, then associate the IDs you get back with the server for follow-up gets, reads, calls), it's just annoying boilerplate.

Maybe we build an actual Host abstraction into the SDK, which has multiple Clients?

Research direction

Start by reading the TypeScript client SDK entry points and the related Python SDK issue #9. Define how a Host containing multiple Clients should send list commands and associate returned IDs with their servers for follow-up gets, reads, and calls. Done means the abstraction supports simultaneous client-to-server connections without repeated application boilerplate.
