[texhax] does TexLive mess with hard drive or any other part of computer?

Thanks for the info.

Reason I ask is I am wondering whether my kids could use the TexLive DVD 
on computers at school.  They are Windows boxes, win2000 I think, with 
DVD drives.  School would frown on any software that altered their 
configuration, of course.

I'm not sure, but I think each child has a directory on the network 
server in which to store their data files:  H:\susie, or whatever.  Do 
you think that TexLive could use that directory for the .fmt files, etc? 
  Or does it have to be the C:\ that is the physical hard drive in the 
particular computer?  And are those files executables that could be 
potentially harmful?

I will, of course, discuss this with the computer people at school. 
Simplest solution, I know, is to persuade them to install Tex 
network-wide.  No reason not to install it, except fear of the unknown 
and institutional inertia.
