I just wanted to confirm that CW-LMS-3.0-5K-K9 (5000 devices) can be installed on a single standalone Windows server box. I've seen some documents which indicates that it requires a multi-server environment. The box I'm thinking of is a dual proc (3.0) w/ 4 gigs of ram.
You should definitely go with the 5K license price-wise. You can install all the applications on the same server. You just cannot manage more than 3000 per application on this server (which won't be an issue given the aforementioned numbers).
