Forget winesd, on the Xen PV have snd-dummy loaded. If you are using X-Windows
and XDMCP to connect to your remove hosts you can have them set the PULSESERVER
on login by querying out the hostname on the $DISPLAY string and setting a
global environment variable.

I use KDE and kdm which has a /etc/kde/env directory where it whatever script
you have there on login to set global environment variables. In this directory
I have:

/etc/kde/env/pulse.sh:
PULSE_SERVER="${DISPLAY%%:*}"
if [ -n "${PULSE_SERVER}" ]; then
        export PULSE_SERVER
fi

/etc/kde/env/esd.sh
ESPEAKER="${DISPLAY%%:*}"
if [ -n "${ESPEAKER}" ]; then
        export ESPEAKER
        export ESDDSP_MIXER=1
fi

Maybe gdm has similar environment setup?

Oh, if you are using a distro where alsa isn't auto redirected to pulse
you will need the pulse-libs, alsa-pulse plugin and an asound.conf like:

/etc/asound.conf:
pcm.pulse {
        type pulse
}

ctl.pulse {
        type pulse
}

pcm.!default {
        type pulse
}

ctl.!default {
        type pulse
}
