So how should the larger distributed IXPs solve this? Provide optical DWDM 
transport? Dark fiber? What if there are no chassis on the market large 
enough to accomodate creating a single switch for all customers to connect 
to? Have multiple L2 domains and require people to connect to multiple 
switches? Even bumping people off of an existing switch when that is full, 
to move some traffic over to another new switch chassis?

What about buffer requirements? If you want a buffered switch, it 
increases capex and lowers number of switch-models that can be used. 
Microbuffered switches may lose packets in microbursts when ports are 
being run (near) full.
