If you have not already looked into the openSUSE Build Service, you ought to give it a look. A few developers have started to, mostly those posting on PlanetSUSE.org, but it still remains a relatively undiscovered powertool for most.
The Build Service lets any open source developer use our build systems at Novell to automatically build his/her own packages for SUSE-based distributions–as well as Fedora, Ubuntu, Debian and several other distros. When your package does not build, you get notified as to why. As distro updates occur, your packages get rebuilt. You can even roll your own SUSE-based distro. All at no charge.
Frankly, having a service like this totally rocks for open source developers. I’m quite surprised that no one on the Linux press beat has yet to pick up on this.
