asyncio byte data transfer

[Skaperen]

each client that connects to be served will have its own separate instance that serves that one client. in order to do things like having a chat between clients, the these server instances will need to be re-designed so that they can do a message exchange. there are many schemes to do that. but. one thing all of them will have is some means to identify each client. you will want to make that be secure which means all communication with clients will be encrypted (use TLS) and clients will login with a password or asymmetric encryption key. then each server code instance will know the user name for who they are serving. and you will need to choose the way you will have it do message exchange (how to no only send a message between instances but also send it to the correct instance). how many instances do you think will be running at one time?
