If just playing or recording a file, it might be desirable to avoid

But in this case performance is not an issue anyhow :-)
Logic does all it's internal processing in float (or even double, if
necessary). I would expect that every even half-professional audio
application does so, too. You don't have to deal with clipping and you
can do real math without converting (converting float->int is extremely
costly on a PowerPC!). How much effort is even a volume control with
clipping in integer math? It is one cycle in float...
BTW: On of CoreAudios real advantages _IS_ multi-client support and the
customers love it. Only because they _had_ to use ASIO under Mac OS 9,
doesn't mean that they prefer the old solution.
Ok, users don't like system beeps on their audio hardware, but they can
change that in the system preferences, so this is no longer a problem.
I really would recommend not to deal with hog mode (BTW: we never
tested Logic with hog mode, because AFAIK no audio hardware supports it
:-), your tech support will be flooded (why is iTunes not working, etc.)
