At least as far as I can see: - port/package management: most users would benefit - improved virtualisation support: a lot of users would benefit - improved driver support: a lot of users would benefit - KMS/GEM for better graphics card support: a lot of users would benefit Can you honestly say the same about handling line rate packet forwarding for multiple 10G cards? I suspect I would rank true multipath storage support above 10G routing, for example. Gary
