If you are contemplating downloading the 3.5GB iso file for Fedora Scientific Live, then be aware that after installing there currently are over 1400 updates to be performed. These require downloading another 2.5GB's of files.

I suspect that the updating of Latex is a major contributor to the 2.5GB's involved.

cheers, Ian
