Your WinNT will be in the lab and linux in your office, so in my view 
it will be a more comfortable environment, than having everything on 
linux in the lab. Comfort was my motivation number one when I started
this project - I do not like sitting in the lab unless it is absolutely
necessary (and in 99% of the cases it is not necessary at all).
