Would you consider adding udpcast, a multicast-utility
(http://www.udpcast.linux.lu/) to the image? udpcast is
small, and adding it would make it possible to e.g.
clone 100 or so PCs from one master at a time. This
would be a great timesaver, since INSERT is apart from
that really superious.
Also it would be great if INSERT was bootable via PXE
without having do run insert on the server (e.g. if you
already have a configured pxe-server).
