Red Hat Satellite vs. Ubuntu Landscape
Solution 1:
I think one of the main differences is the fact that in Landscape you cannot have off-line install, with your own servers, you have always to be connected to the Landscape servers...
Also, Satellite went open source, called Spacewalk, i would kill for an opensourced Landscape...
Anyway, there's a project for supporting deb files on spacewalk, but I don't know what status does it have...
