Real nice script, I was going to create something like this myself, expect focus on the logging, users can customise what is logged etc. However I did not really care about displaying the data, I guess I intended to take the .xml file it created, and a script hosted by myself would process it.
The great thing about this script is it's professional. I am sick of seeing half done scripts made by people who are simply trying to win the contest, a script like this has been planned and coded well, it is a sure deserving winner of something, I'll even post about it for you on my website if you want
