Sure you can insert all the language you want with the lastest vLite 1.1 beta ! You must download the language pack of the language you want (FR, IT, GR, etc ) and you can add it in the unattend DVD that you will create with vLite ! They can be found on Windows Update on a Ultimate version (i don't know if it is possible with an another, i don't think, maybe enterprise edition that's all). The Language pack is an LP.CAB file for every language, so you must create directories "GREEK" with the LP.CAB inside. And during the installation on vista, you can select the language you want to install EDIT : Or the easiest way, you install one of your VISTA ULTIMATE, US or GREEK, and with Windows Update you DL the Language Pack you want, and with the control Panel you can switch between US and GREEK when you want. More practical i think ...
