It didn't used to be very compatible with server-type networking, but
that's exactly what we've been working hard on for the past year or so.
Bonding, bridging, VLANs, an Infiniband are all supported by the current
NetworkManager 0.9.8, though it doesn't (yet) cooperate well when
external tools touch things.  That's going to get a lot better quite
soon.  The 0.9.8 GUI and nmcli both have support for all of the
aforementioned interface types.
