  The same is true for networking.  Someone has made

Coincidentally, I'm readying an Ethernet cartridge for the
C64/C128 this
week for production:

It's jumper configurable (since this crowd loves jumpers) to allow a
theoretical maximum of 16 ethernet cards in a C64 :-) (theoretically,
since I'm not sure what the point would be, and the bus would degrade
too far after a few carts).   I can definitely see value in 2 carts,
though:  C64 firewall :-) (or 3 cards, with a Internal, External, and
DMZ segments...)
