so in other words, if you want wscale to be able to go to 1 but for things who don't support wscale you want to retain the same current functionality, add 65536 to the current value of whatever (send|recv)space you're talking about. wscale of 2? add 131072 from the baseline, etc. go too high and stuff won't work at all -- jared
