A "distro" is a DISTRIBUTION. It's very common in the Linux/BSD worlds. Think of it as a "flavor" of an operating system. So, what I meant by this was exactly what I asked... if I vlite my Vista install disc, can and will it still activate properly? Since I haven't received any responses and I'm not known for having the virtue of patience, I just finished using vlite. It is burning as I write this. I'll soon have the answer to my own question, I guess.
