Theoretically, yes... but perhaps this is a bit over the top. For the
space we are aiming...

 - the XS services will bottleneck well before saturating 1Gb/s traffic
 - 'upstream' services that the XS is routing will bottleneck well before 1Gb/s

if we see a 7-AP setup, it will be there to support either a large
number of laptops or a location with obstacles that needs many
antennaes. In any case, it will support laptops mostly peering w
eachother.

If we are designing for a "client base" of laptops that we actually
expect to saturate 1Gb, then... we need to start recommending a
mid-range server cluster, perhaps a SAN, all costing a few megabucks
;-)
