Andrew Orlowski argues that Samba 2.2 has one tangible benefit
that makes it worth a download: Samba makes Microsoft Client Access
Licenses — mandatory for printing and basic file sharing in a
Microsoft environment — redundant:
“CALs are a piece of tollbooth revenue that Microsoft has been
singularly reluctant to drop. It’s pretty much regarded as sacred,
in fact: even Citrix thin clients are obliged to pay the Windows
CAL tax.”
