Thank you Capricorny,

and sorry for the delay. We just returned from a conference where we started the BatPro program in another city in Romania.

With your script we managed to shrink down the ISO to 2.8Gb and probably if we search more we could go further. I like how targeted directly an entire category or set of programs.

Regarding the use of another ISO, it's possible that we could go with an Ubuntu ISO. I don't know why but we had problems with nvidia cards in old computers where Knoppix 7.4.2 was loading a wrong nvu module and we were ending up with a black screen in graphic mode. This problem did not appear with Ubuntu 14.04.

Please feel free to propose more strip down scripts. We use LXDE, wxPython, espeak and VLC.

Regards,
Rares
