[Planetlab-devel] questions abouting running an independent myplc

Wed May 21 18:36:27 EDT 2008

Marc, Scott, Thierry, and Roberto,
Thanks all for your replies!

We'd like to replace the role of Ethernet with a wireless interface,
be it WiFI or a 3G modem.

We volunteer to work on BootManager and NodeManager for the various
scenarios
we envision for our case.  Whom should we contact?
