I know this was spoken about and many people 
wondered how it could be done to share multiple internet connections for 
schools. I just found this to be interesting reading so here's the 
link...
 
 
"The impressive part is the ability to 
combine several broadband feeds. This is an option (it doesn't happen out of the 
box, but it's built in) - if there are 20 houses in the Mesh, but only four of 
them have broadband, all users can share all of those lines. It does add to 
network traffic; there's an estimated 10% increase in wireless load, says 
Lander. "
