I apologize for being somewhat off topic... I've got a fair amount of SPARC hardware (v210 through v490) and 32bit HP DL360-380 hardware that I'm looking for creative ways to dispose of or to donate. It seems like a waste to send it to metal scrap, if anyone has a more creative way of disposal

I think you have your latency numbers backwards. In my experience, HSDPA has higher RTT than WiFi. Why would you limit your Wifi to A/G? If you're using 5Ghz (A), much better to go to N than A. N has slight advantages over G in the 2.4Ghz realm. Your stated packet loss rates are obscenely high and
