So what are the chances of making this work with Uthernet too?

They are good, and I've been keeping that in mind.  There's no change

required at the server end; it's already in place.  The trick is going

to be the driver size.  The IP stack isn't skinny.  Maybe it could all

stuff into $800-$1fff...

Maybe it can be an abbreviated IP stack to just transfer the packets
back and forth?  Have some initialization code that can be unloaded?
I have some basic Uthernet sniffing code left over from VM02...

That's a good idea.  With pre-initialization, we'd lose flexibility, but
we could eject everything but what's needed for UDP.  It would probably
entail building two stack versions - the usual full one, and a
stripped-bare version that just took the now-digested configuration
block.  This is definitely turning into a loader plus relocated driver
kind of affair.

Shouldn't IP/virtual drive booting/mounting be done in the firmware so there is no 6502 IP stack? No need to change any software or add drivers?

I'm thinking CFFA3000 could leverage a USB/Ethernet or USB/wifi device and pull off the same trick (with firmware updates of course).

This is how the Apple Workstation card works, right?
