@davidgerard @R3yScale signal groups support 1000 participants, and video chats supposedly will do 75
an idea (no warranty on how good it is) is to use libsignal to implement a signal client with a concept of a signaling group chat, used to implement groups of groups and present them like how discord presents servers and channels. signal’s existing invite URL mechanism can be used both to invite users to the “server” (signaling group chat) and manage channel membership.
