I never realised before, but Windows based Internet cafés violate Microsoft’s license terms, because:
Windows desktop operating system and Microsoft Office system licenses do not permit renting, leasing, or outsourcing the software to a third party.
Interesting.
Now however, by paying an extra licensing fee to Microsoft café owners can become legit.
Seems to me that a Linux based kiosk with OpenOffice.org is just going to become even more attractive..
