The thing is that the national CAAs still have a few degrees of freedom to play with. JAA can't force anyone to "copy-paste" the JARs (in it's purest form) into the national regulations and throw away everything that was in use so far. Well, they do encourage everybody to do it this way of course ("Standards, folks, standards !"), but that's the limit of the current system.
Once EASA will be in place, it seems that the national CAAs will become quite like the FSDOs in the States: just a counter doing the paperwork and following the guidelines drawn in a galaxy far far away.
Unfortunately, by judging the contents and the speed at which the monthly gatherings of all the "heads" of all the JAR CAAs are going, they're not in hurry to give up their last privileges (if you can call that privileges), even though there's clearly no doubt the EASA will not leave them out of job. They spend more time talking about "what should we do about those folks who are NOT YET in the JAA-system ? Should we invite them to our monthly party ? How are we going to spend all that money ?", than talking about "what should we do to improve the system for the folks who ARE in the JAA-system ?"...
