A way to distinguish guest or AS-ghost room members (SPEC-361)

[matrixbot]

It would be useful if a client can distinguish at a glance of the members list (i.e. the set of m.room.member) events which users are guests, which are ghosts of which ASes, etc...

One way that this could be done easily is by adding another profile-like field, to be supplied along with the displayname and avatar_url fields there.

Yup. this could be done by extensible profile data, namespaced to the bridge itself, but i'm a bit worried that it's trivially spoofable and unnecessarily 'magic'. It feels slightly nicer to me if the AS was to 'sign' the user into participating in a given usergroup - i believe Erik's plan for user groups is some kind of crypto-based mechanism where the group owner signs the members to prove their membership. Then there's no spoofing, and we can put whatever metadata we like on the group itself?

It would be really great if this could be implemented. As it stands, the bridging situation is really awkward, especially when there are 2 bridges involved, because you just can't tell with whom you're talking.

I'm constantly finding myself, browsing the web (GitHub), just to figure out who that is.
