Yes, you'll effectively be limited to window scale of 0 which puts your 
maximum buffer at 64k. You won't see a problem unless your bandwidth 
delay product (BDP) exceeds that value. You can determine your BDP by 
multiplying the bandwidth by the round trip time.

Yes. This will impact all of your connections.

Well, its not something that the linux kernel people need to fix. In 
fact, having this problem come up is probably a good thing as it will 
spur people to fix the problems in the intermediate boxes.
