Seam supports the notion of at "conversation context", which exists within the context of a session. You can have multiple conversations running in parallel within a single session. It tracks this using a conversation-id. So, I'd suspect they need something that they can map to something like "session-id:conversation-id". Not sure what Gavin/Burr has in mind - perhaps they've no intention of supporting anything beyond an equivalent of a session-id.
