+Thanks, Nicolas.
+
+I remember having seen a choice between ka-run and ssh, when I looked
+at the tool.
+
+ka-tools has been obsoleted after Mdv 2007, or am I wrong about that?

+It would be nice, in case we're going to have an educational DVD
+somewhere in the future, to know whether this MCC option would be an
+appropriate tool for people in charge of some school computers to
+maintain them.
+
+So there is this tool, and there is urpmi --parallel and
+drakrpm-edit-media --parallel=alias,host  (be in parallel mode, use
+"alias" group, use "host" machine to show needed deps)
