Hi Derek,

Ugh, sorry to hear that the PA related sound stuff isn't going well.
Incidentally on my machine (9.10), using the version of the plugin that
ships with the Scratch package (with latest PA updates) I don't get any
stuttering on playback - although I did when I tried the plugin with the
Squeak-vm submitted to Debian recently. But I imagine there are a lot of
other factors I'm not aware of.

Re: other distros. I have heard a few requests for a Red Hat compatible
version. I think the next generation OLPC will have a RH based OS?  I was
thinking of trying "Alien" package converter (from deb -> rpm) to see if
that would be a good solution. I asked a few community members to try it but
haven't heard back.

Re: KDE - that would be great, but again I'm not sure how to do that. We
still have the bug the breaks installation on Kubuntu (installer tries to
write to gnome only file to register file type I think). If we could fix
that, we might be able to try the current package using the ALSA plugin on
the off chance that Phonon might emulate the asynch stuff properly.

To sum up, supporting other Linux distros would be great, but the primary
goal is plain old Ubuntu. But if Gstreamer made it possible to hook into
lots of other options, so much the better. I would think the same could be
said for choosing any other other popular widely available sound library,
like SDL <http://www.libsdl.org/>.
