I don't know what price they're currently charging, but it's not going to be very cheap. > Are you able to do the following: you have (for example) two machines, > W and L.

Technically that might be possible, although you're likely to run into trouble with interrupt or isochronous transfers. Clearing halted endpoints would also be difficult, since the netchip driver doesn't tell (or doesn't know) when such things happen. In practice there isn't any software I know of which can do that, although it might not be hard to write a driver for it.
