Any X10 activity loggers that write to a CSV file?

[Tuicemen]

I have a small app that reads several (5) CSV files and pulls selected info from each and writes a new file CSV, XML, TXT or HTML.
I'd like to include some X10 activity I'm interested in following.
Before I go ahead and create a X10 CSV file app, I'm wondering if anyone has created such a thing and would be willing to either supply the app or code.
There may be others interested in this as well.
