[volunteergrid2-l] adding files to the grid

[Chris Brown]

While not directly answering your question, it might be good practice to 
run ntop on the node.

Perhaps allow others access to.

This would help determine the node's max upload/download speed (peaks on 
charts) as well as how busy it was with other traffic at the time your 
were uploading your file.
