Firewire and USB are pretty digital. Firewire can cart about huge
amounts of information accurately and precisely. {DVD sound, video,
etc...} Both of them are capable of network connections.

Straight network cables can manage to convey information fairly accurately.
It seems to me that your "digital" connect is only a conduit for information
that's encoded and decoded at either end. I'd think the "intelligence" to
be an attribute attributable to the server and client.

I'm quite sure it's possible.
