Jay,

I understand that each connection would only be allowed  a maximum speed of my upload bandwidth on a single ip.  If I can specify which NIC device to TX on per ip, It should work.  I am doing it right now, the problem is i have to add the ip to the routing table by hand.  I am looking for a daemon which would manage the connections to do this on a larger scale.  In a sense, do the work I can do but 24/7 when I am not around.


You make very good points, but I have determined since my first e-mail that it can be done.  Now the question is how.
