Thanks Paul. I will give it a try myself. Just one last question :: I suppose that 'echo 0 > "/sys/class/net/eth0/lbs_mesh"' is a hack that is olpc-customised. So, I will be really grateful if you could point me to some docs (a wiki page may be), that provide information as to how this hack affects, and is affected. Thanks for your help.
