well, they could be used in a fashion like ISDN uses channel bundeling,
but this would require *significant* changes to the network code....

note: i don't mean two cards on the same cable, but two cards = two segements
and the target computer would also have to have two card on two seperate
segments. anyway, all you'd get would be 20MBit/sec at max., so if one
wants better network transfeer, why not put in a 100Mbit card ...
