With the Sugar environment, do all laptops connect to the access point or is
it a mesh where traffic is relayed or tunnelled through one connection, and
it is only the internet requests that go through the access point?
XOs can connect via ad-hoc or through an access point. Ad-hoc requires
one XO to act as the hub for the others, but only scales to 5-10 XOs.
An access point is needed beyond that. Once you get beyond 20-30 you
should start thinking about implementing an XS School server, which
runs an ejabberd instance to manage the XMPP (jabber) traffic.
XO-1s had mesh capabilities in hardware, but this no longer applies in
the XO-1.5 and XO-1.75. Ad-hoc has taken its place.
