Now, this is interesting. how would you like to cut down the size of a vista install to up to 10% of it's "full" size?
vLite will create an install image of Vista with your choice of features stripped out of it, from screensavers to firewall to universal plug and play. you decide what goes into your vista install. Pretty cool. I can use something like that. Especially on virtual machines!
