Technically speaking the only problem was the interaction with kernel-power, or the incompatibility. This should have been fine if ppl just had accepted the situation, but there were quite many attempts to fix it, most of them technically too challenging to be presented on this forum. Nevertheless, the "user experience" of this version of multiboot was so lousy, that I decided to recall it. Next version of multiboot will be only available through an integrated NITdroid installer. Available soon.
