I agree with you, Lee, it is what i did with my own tool. Native logs 
are converted in CSV files. But some logs are not simple to convert :
- java exceptions
- java threads dumps ( different for every JVM : Sun/Oracle, JRockit, 
IBM ...)
- java heap dump summary ( same remark)
- verbose GC logs (same remark)
- multi-lines log enregistrement (xml logs ...)

Others are more simple :
- acces logs that are Common Log Format ( CLF) or CLF extended compliant 
( Apache, Tomcat, IIS, WebLogic, Websphere ...)
- Log4J
