Today the UI and the server run as a single app. We're working on separating that, so you could technically have one server with multiple clients. But even then, for collaboration with others, there are two issues with sharing a login session: (1) the system doesn't know these are two separate people, and (2) it has access to someone's email etc. - if it doesn't know who the user is, everyone gets the same access and can run anything.

That's why we're exploring a peer-to-peer setup for group chats instead. Each person keeps their own machine and data, and the assistant knows who's who and can ask the primary user for permission if the secondary user wants to run something non-trivial.
