what level of realtime performance has been accomplished on the

604e-s to the g3 processors?

1) if you can do what you want to do in some other mac app than csound,
		then i would go with that.  

2) Mac Csound currently needs some major
		revisions to take advantage of current processor improvements.

3) if i had a grant/funding i would do it. (otherwise i will have to get a
		real job as dave and mike have)

4) no such thing as realtime on a computer

5) we will always want performance to go beyond the current realtime
    benchmarks.
