That sounds doable. I can easily create a section for Klik just like the ones I have for deb and rpm repos right now. It would be great to align that with the Klik2 launch.
The only part that really takes much work is getting the names of the apps that have Klik versions into my database so the link is only shown when appropriate. What I do now is run a script every day that checks for new deb and rpm versions. With Klik I envision referencing a text (or HTML, XML, etc.) file that I can parse and cross reference versus the package names. As long as the Klik team provides a file with consitent formatting for me to grab the package names from then I can do the rest.
