 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.
