Full blown 64 bit apps will be here sooner than you think. There are
some real advantages to running in 64 bit mode for applications. For
instance, on Intel hardware, you get twice as many registers. This can
boost throughput and/or calculation speed for some apps. Also, those
apps that have large sample banks and want to use more than 4GB of
physical ram have no choice but to run in 64 bit mode.
To facilitate the transition, AULab and HALLab already run in 64 bit
mode today. Just not by default. To get these apps to run in 64 bit
mode, just get info on the application bundle (in /Developer/
Applications/Audio) and uncheck the "Open in 32 bit mode" box.

Theoretically, support for 64-bit AU would require *every* AU host
to be rewritten as a 64-bit application. It's pretty tricky to
rewrite a GUI application for 64-bit, and all popular AU hosts have
a GUI. It's going to be a long time before there is any host that
would support a 64-bit AU anyway. This "limitation" is merely a
practicality.

I finally figured I had 64bit set (x86_64), assuming leopard is all
64bit. But it isn't it just supports 64bit, but doesn't use it in
AUs. Which I suppose is two avoid deprecating lots of installed AUs.
