Questions about KDE4

[Hendrik Sattler <debian@hendrik-sattler.de>]

Hi,

some people here obviously already tried it. I cannot (only one system without 
a CD writer) and have some questions:

First: is it possible to try it in something like VirtualBox?

The KDE people tell about lots of features but leave a lot unclear. Like 
Phonon can reroute audio in a central way. However, does that require that 
applications actually use Phonon for audio, then?

I am missing a overview over the state of applications: which ones are already 
KDE4 ready (completely, I mean) and which ones are hopelessly left behind and 
still at KDE3?

I can still run KDE3 applications on a KDE4 desktop but what happens to 
KDE3-desktop things like system sounds for such applications (arts is 
probably not staying around). Is dcop compatible with the new d-bus stuff?

Thanks

HS
