You could use the nano-patch (http://www.ssi.bg/~ja/nano.txt) and the equalize
option in the multipath route configuration. but from what i understand, the
traffic is coming 'into' your machine, the splitting of the incoming traffic
has to occur on the other end of the connection. The nano patch will equalize
the traffic that goes 'out' of your system. So if somebody downloads data
from the gateway, then the data will be split equally (or according to the
weights) over the outgoing connections.
hope that helps,
ashok
