The least common denominator in the XO-1 and XO-2 clients is a
connection to an access point.  So making the XS (on any hardware)
provide a standard 802.11 access point would probably be the easiest
path forward.

As I recall there was some step in the XO-specific school
"provisioning" (antitheft DRM?) that only works over the mesh.  So if
that hasn't been fixed, either deployments would have to turn off the
DRM, or OLPC would need to revise the firmware and/or initrd to handle
this interaction via ordinary 802.11 access.  Or they could just throw
away their DRM-choked devices, as many others have had to do when the
big DRM server in the sky went away, and take a lesson from that.
