That actually looks quite useful. I keep a bunch of search shortcuts around for poking in other distro packages to look for patches, missing build options, and other things. I was just never able to find anything for OpenSuSE nor the git repositories for Debian. Having a one-stop-shop for such things would be nice. Also, a website which aggregated what patches for a given package were floating around in different distributions would be great. A translation database between distro package names would likely be needed and version tables to compare current versions in different distributions would also be a useful tool. Most likely not an easy problem however with the different practices of each distribution.
