Yes, but I don't think we have achieved all the goals in it, so I won't call it "done" - > Great job describing scenarios and motivation on both.

It will be *fantastic* if someone can document this to the last detail, and update it every time we change the code. In the meantime, read the source. The traffic control algorithm is here - line 17 and 28-37 are interesting: http://dev.laptop.org/git?p=users/martin/ds-backup.git;a=blob;f=server/backup-available.py;h=b7a2dab0115601737c641cb5e2bb2038a9963461;hb=413237674d734101dc8c22639a96eba35ddac2a4 > 4 - Can you set the "quota" per XO?

Again, need for documentation helpers. Good docs take at least as much time to write as the code itself. > On http://wiki.laptop.org/go/XS_Blueprints:OTP_root_passwords > > 1 - My only question is if we have a lead customer for this.
