Comment 3 for bug 201046

The DVD should work whenevere there is NO internet connection (provided /casper/filesystem.squashfs is there and .disk/info matches the one in the LiveCD). If there is an internet connection Wubi will be able to retrieve the MD5 of the LiveCD and things will go sour. Please test such theory once checksums are in the metalinks.

What I can do is to allow for a switch in settings.nsh that will disable remote metalinks, and add a max ISO size to calculate required free space more accurately. IF that is approved, you will need to change such flags and recompile your own Wubi version. I am afraid that copying over only a subset of the files is not doable at this stage.
