Ok, that is consistent with my experience. Since I just started using ALSA 
(with current versions 2.4.23 and 2.6.0) and I already like it ;-) I think 
I'll add a native ALSA output plugin. I usually don't use aRts since I have 
all kinds of troubles with aRts.  Some of my most used programs like 
gnomemeeting (ok, that's gnome and not likely to work with aRts) but also 
kphone (which is a KDE program) don't work with aRts so I stopped using it.

Hmm.. interesting..
