RMI sits on top of a TCP based transport protocol. I think that
a bytestream over IP sockets would work fine. But I still don't
see much real value in networking. Cool, yes, but what for?

Well, you can use UDP is IP is not good enough, but you'll need
to write a protocol that resends if packets are missed.

Again, what is the use of watching someone else's EEG in real
time remotely? You could just record a session and send the
file if you want someone else to look at it from elsewhere.

Namaste,
