.. also usefull would be Microsoft SQL cals.
SFAIK There is currently no code to do this, but it should be "doable".
BTW I have noticed that even Terminal Services itself is particularly poor at tracking CALs, owing to the rather bizarre way the different versions of Terminal Services treat their CALS. TS 2000 has a tendancy to issue temporary CALS to valid TS users and both genuine CALS and temporary CALS (which eventually expire) to Wyse Thin clients, leading to Wyse Thin clients with older firmware eventually being unusable with the TS2000 box they were bought to serve, but being perfectly usable with TS2003...
