Some interesting responses.
When I raised the idea I had in mind that the NIC would be offered, but that's pretty much it apart from supporting the software side of install, which I think, from what Debsy says, is done already. NTL would make it clear that they're just providing the hardware and maybe an install manual, and have no responsibility if you wreck your PC (unlikely).
I'd agree that the focus needs to change from USB to Ethernet because (as others have said) not only is its prevalence increasing, but it's actually easier to install than USB for many people.
So it seems that it's
for providing a NIC but
for switching emphasis to Ethernet as the "connection of choice".
