I have a series of CGI scripts that I use right now for client 
functionalities:

http://www.perfsonar.net/activeServices

These use an API written in perl so if you are interested I can most 
certainly pass these your way and offer any help on their use.

Subscribing to  would be a good start for 
developer-ish talk.  I believe we do have an effort started on something 
very similar to what you are proposing (analyzing the gridftp logs 
specifically), I am CCing Dan Gunter from LBL who may know a little 
about what is going on specifically with that project.

Thanks;
