1. A2A is on our roadmap (still exploring), for agents built on Rowboat to communicate with external agents. I assume that's what you mean as well.

2. Rowboat agents are technically stateless in that they do not store any messages and state between turns. Our HTTP API [0] requires previous messages and state to be explicitly passed from the previous turn to the next turn. For now, the state is pretty simple - just the name of the last agent that responded to the user. This allows the system to start off directly from where the previous agent left off. The Python SDK [1] manages the state for you. Does that make sense?
