At least debian and gentoo include their own version of lesspipe in the less package. Nor sure if we should do the same or include this package here. I use this since a week or so and it works well so far. I'm not very creative on creating descriptions. Please feel free to change it. ;)

+can be used. By setting the environment variable LESSOPEN, less can be
+enhanced by external filters to become even more powerful. Most Linux
+distributions come already with a \"lesspipe.sh\" that covers the most
+common situations.
+The input filter for less described here is called
+\"lesspipe.sh\". It is able to process a wide variety of file
+formats. It enables users to deeply inspect archives and to display
+the contents of files in archives without having to unpack them
+before. That means file contents can be properly interpreted even if
+the files are compressed and contained in a hierarchy of
+archives (often found in RPM or DEB archives containing source
+tarballs). The filter is easily extensible for new formats.")
