I'm sort of able to do this. I have an a500 with an 030 and scsi/compactflash. Using dctv I can "watch" videos... with a zorro-2 adapter, you could use a regular ethernet card. I think all of the cards are 10mbs, so I'm not sure what you consider high-speed. But zorro-2 does have enough bandwidth to utilize 10mbs ethernet...
