Microsoft has just release a new Gadgeteer core. http://gadgeteer.codeplex.com/releases/view/105603
One of the great additions in this release is socket indirection that allows for creating hubs. You will never run out of sockets anymore
We have also designed our first Gadgeteer hub. We will release a new SDK to support socket indirection and release the hub in short weeks.
