Viktor and I spoke in more detail.  The use-case he brings up makes more sense to me now. The key observation is that this is not about a "client" in the conventional (or browser) sense, but rather more like a peer-to-peer kind of thing, where the client is just the one who initiates a connection and might be multiple processes running on multiple instances sharing an identity.

I'm in favor of his suggestion.
