Couldn't tell you word one about Ethernet protocols, except that it
wouldn't take much of a stock C64's CPU to handle DMA.  Transferring a 32K
chunk at 1 MByte/sec would happen in, well, 32768 1MHz clock cycles, plus
the time it takes to set up the transfer.

In otherwords, little or no real CPU load.  The worst load you'll have is
interpreting that data and storing it, displaying it, or whatever.

Won't be me that does it :)

An Ethernet connection between your Windows box and anothr computer like
the C64, as far as I know.  Network Neighborhood is just a convenient way
to point to any given machine on the LAN, as far as I know.
