I rather like the free form method of the feeds as they are, but seeing that it does take a relatively long time to download and install a package that might not work with your architecture, it would be very nice to have more info somehow: i.e. machine that the package was built on and for There are a lot of duplicates of certain programs floating around, and it's hard to tell which ones work for which models.
Also, I would like to see if the sources were patched during the build, and if so how. Would there be a mechanism to upload the sources to the new site? I would somewhat like to see the APT method for ipkgs: i.e:
apt-get source $PACKAGE_NAME
or
ipkg install build-dep $PACKAGE_NAME
