Why do you need such a thing, it's a Live CD, you just make a virtualhard with some space and just load in the virtual CD-ROM a Backtrack iso and it boots up.
Had a thought a little while ago. I've noticed a lot of people having trouble installing BT4 to a VirtualBox hard drive. Would there be any licensing/copyright/whatever issue with me (or a more established and known forum member if that would be more acceptable) posting a torrent or a direct link for a VirtualBox drive with a fresh BT4 install on it?

No offense to you but I wouldn't trust your virtualbox image. As a matter of fact if it isn't in the official downloads I wouldn't trust it.
