Double your ADSL downstream by getting a 2nd line run into your house and then bridging the connections? Or building a giant communal WiFi network on your street (assuming you trusted your neighbours) by using all their lines and bridging all the routers? In theory your max bandwidth would then become the maximum your cabinet could support, no? It would be a cool experiment if you could get a load of 50Mb neighbours and join them into a big gigabit network (if you had the hardware of course).
But yeah, is it possible?
