installing linux to network drive

[mastersaibot]

I have a network of windows machines, and I want to run linux on them, but I dont want to make any changes to the partition tables or add any existing files to the hard drives (the systems are running deep freeze and its a bit of a pain to restore them when they've been permanently changed)

I've been using live CD distributions, but I need access to several features that I cant find on a one CD distribution

So I've been considering installing linux on a network drive, then booting to it from a floppy.

I've been given 5 gigs of space on a network drive that i can screw around with, and all the computers have identical hardware. I do not have physical access to the server machine.

What i need to know is: Which distribution should I use, and how do I install and boot it from a network drive?

For the distro I would go with Fedora or White Box. These are a good place to start. You can always use knoppix.
