I still sometimes see people complain that something is "only available through Zero Install". The thing is, the packages downloaded by AddApp work just fine on their own. An 'interface file' is just a list of links to tarballs (much like a web page, but machine readable rather than HTML).

But why not make the feeds human readable too? Add some XSLT and they can be! Load this in your browser:

• Sample feed

It looks like a normal HTML page, but if you do View Page Source in your browser, you'll see that it's actually an injector feed file.

Frequent software releases are a problem for ROX. The biggest problem is motivation: the person in the best position to make a release is the program's main author. But why would I want to make a release of my own software? I already have the latest version!

Originally, ROX programs (like ROX-Filer) followed the Linux release system of having separate stable and developer branches. So, 1.0.0 was a stable release, then 1.1.0, 1.1.1, 1.1.2 were developer versions. Then, eventually, 1.2.0 would be the next stable release. Theoretically, this should allow you to have one very stable version for normal users.
