I'm sure you're right that a driver *must* be required at the sending
end.  There seems to be very little hard technical data available
on how these things work (the driverless ones, I mean).

Some accounts say that it is a feature that Microsoft added to Vista,
which will mean it's proprietary, undocumented and probably based on
SMB.

Others say it uses the USB Host to Host Networking, which is a
standard and supported in Linux with the usbnet framework:

http://lxr.linux.no/#linux+v2.6.31/drivers/net/usb/usbnet.c

but it must still need some software to do the USB mass storage
presentment, unless it does SMB over the network (in which case it
likely won't work with your DVD player).

If you buy one, do let us know ...

Rich.
