That would be very cool Myron.  I won't be around next month, but I do have 
some interest in the subject.  This is way above my ability, but my goal is to 
write a driver for a NIC.

I've got a handful of Racore multi-personality NICs.  (9348? I can't remember 
the designation and they're boxed up right now.)  These use a TI Thunderlan 
chip to drive the 10/100 interface, and a swappable module you can pull out to 
give the card either an ethernet RJ-45 interface or a fiber optic ST interface. 
 The cards are supported in FreeBSD & various Linux distributions when you're 
using the ethernet module.  All the ones I have have the fiber module.  The 
thunderlan module loads, but then is unable to take advantage of the card.

I don't have any hardware info about the module, but I've been able to google 
for the various controller chips.  Apparently the one that controls the light 
signals is a fairly well known HP unit (more google hits for the HP chip than 
for the entire Racore card).

Anyway, something to kick around for a while.

Cheers,

James
