Yes, and we should definitly target the different maintainers, or even
better if possible, maintain the Jambi packages on these systems ourself
to get up to speed on Qt Jambi. At least fedora/suse (with rpm) and
debian/ubuntu (with deb) should be supported.

Wasn't this a bug in JVM 1.5? Again, the debian/rpm package could be set
up to require a certain version of the JVM. This would automatically
install/upgrade when doing a apt-get install qtjambi-runtime. The
package deployment system is one of the really strong features on Linux,
so being able to comply to that is certainly a must if you want to reach
through to the open source community out there.
