>I personally don't see the benefit of replacing the IP65 software IP 
stack with the W5100 hardware IP stack for the "classic" ADTPro disk 
transfer tool. Especially as support for the Uthernet I and LANceGS 
still requires the IP65 variant to be kept alive. 

I think one of the potential user benefits of the W5100 stack will be faster transfer speeds. The bottleneck for data transfer with the Uthernet II looks like it will be the Apple II CPU, so offloading processing to the W5100 should make those 3.5" and hdv transfers much nicer.
