Avatar limits

Does anyone know about how many avatars can be resonable supported in a single Unity scene? This is for a web based MMO I’m working on. Assuming band width is not an issue I’m wondering if there is a practical limit to the number of users who can be logged in at the same time? Is there a point when the video cards in each local machine will just choke trying to render a large number of avatars?

There’s always a limit, but I bet you’ll run out of meaningful places to display avatars on the screen before the user’s machine becomes unable to render them all (barring massively complex avatars)

Thanks very much, Vincenti. You put a lot of minds at ease here on this end.
