[Blind-sysadmins] Microsoft SCCM again.

Hello, I'm in a position where I should recommend SCCM as it would fulfil a number of needs. · Silent software deployment · On demand software deployment · Replacing WSUS · Software inventory · Replacing some group policies. Can anyone with SCCM installed tell me if the latest version will allow me to independently administer these areas please? Novell Zenworks is the currently used deployment system but I'm encountering a few things that it just won't do as well or won't do at all. There's about 10000 workstations and about 500 servers. About 40% of the servers are Linux based. Suggestions very welcome. Thanks
