choosing style according to net speed

[Say3]

hi , i'm looking for automated test speed then choosing style , for example :

net speed Style

28kbps and less redirect to /?sytleid=#1 when Style #1 " no hacks , no ads , very fast"

28kbps <> 56kbps redirect to /?sytleid=#2 when Style #2 "fast but with some ads "

more than 56kbps redirect to /?sytleid=#3 when Style #3 " Ads , Mods , Graphical "



this is my idea ,

for exampel when I have domain :

www.test.com

forum path is :

www.test.com/forums

& i have index.htm in my forums dir , when i visit my forums dir it checks my speed silently and redirect me to the chosen style .

for Example :

Please wait while checking your speed

any body can do that for me plz ?

Sorry for my bad English
