On the XO-1, the answer was "reverse-engineer the Libertas firmware,
recode Cerebro from scratch in C to run at the network layer, even when
the CPU is off, and write a new kernel driver that can interface with it".
 Now that XO-1.5 can no longer forward packets in suspend, reaching parity
is somewhat simpler.  It still requires, at a minimum, that someone
complete the abandoned Telepathy-Synapse connection-manager.

In short, it's a major engineering effort involving 802.11 and Telepathy.
 I would love for someone to take it on, but I haven't heard any noise
about it in months.
