Sorry for being ambivalent. We can of course revisit each design decision we made for RFC 6455 framing and search for the optimal again. But as: - one of the main philosophies behind WiSH is compatibility with WebSocket in terms of both spec and implementation - the WebSocket is widely deployed and therefore we have a lot of implementations in various languages/platform - most browsers already have logic for the framing - the framing is not considered to be so big pain inheriting the WebSocket framing almost as-is is just good enough. Basically, I'm leaning toward this plan.
