The network stuff would be nice but it is the individual package installation/removal that is needed (at least by me).
There was a point (in the FC1 development cycle IIRC) where x-config-packages could install (and remove?) individual package but this got dropped because of some problems. At the time there was come comments to the effect of "we really need to do this right and redesign the whole thing with system-config-packages and up2date merging" (IIRC).
I think a lot of system-config-packages is going to be the subject of a discussion sometime soon b/t me and katz and others. Specifically, figuring out if we can make s-c-p frontend for yum in an intelligent way.
