Great news! Thanks to your team for working on this.
As far as beta help, I would hazard a guess that the pool of Xandros users is really small compared to Ubuntu, CentOS/RHEL and Fedora - the dominant players in the field whether it be home users or enterprise desktops. Do you have an expected timeframe when deb/rpm files will be available for these distros?
Then there's KDE vs. GNOME -- will the tool run with QT libraries alone, or does it actually require the entire KDE library set to operate? A QT version would at least run under GNOME without too much hassle, but a KDE only build is a real kicker - many don't have any KDE installed. (of course the reverse argument holds true for GTK+ & GNOME, going the other way)
