-That reminds me, I've been thinking about the possibility of fiber as a

-factor.  To be practical, the implementation would be constrained as

-
-	1)  Bandwidth appropriate to cheap optoelectronics and serial

-	2)  Bandwidth fast enough to beat (or at least tie) what it

-	3)  Cheap, simple connectors and cables.  I recently read

-	    light from higher angles, which should also imply that
-	    the connectors don't need to be a precisely made (any
-	    comments on this?).

-So, is this reasonable?  What are the limits of "cheap" opto-electronics
-(for me, cheap is < 10$ for a transmitter and reciever, with an expectation
-that it could be 1/10 that for large quantities in a year or two).  If it's
-cheap enough it could be applied to interconnecting digital audio and video
-components too.

At AMD we have toyed with the idea of building a SCSI cable using our TAXI
transceivers (32-140Mbit serial data rate) and fiber. We estimated that the
cable would probably cost $75. I suppose a large market would drive the cost
down.
