Nope. Routers can look at anything in the packets which is not encrypted. They can also measure server response (by packet stats) directly or via SNMP. There are all sorts of things that *cannot* be done on the server without introducing all sorts of p2p communications requirements. As I said, this was all done 10 years ago. However, you may not be able to wait until the linux router project picks this up .... (but it might be worth looking to see what is available). -- --gh
