According to the info at http://www.squarebox.com/upgrade.html, CatDV server can be used for licensing desktop software. Does that make the desktop licenses floatable? That'd be a pretty big deal for us. We have a large number of users who would only need periodic access to the software, but would need the full-featured client.
No it doesn't. See the following from the 6.7 release notes:
"Please note that using the CatDV Server as a license server does not change the basic license terms. Licenses are not concurrent or “floating” licenses and you still need one license for each machine you use CatDV on – once a client machine has requested a client license it uses up that license for that day and prevents any other machine using the license until the next day."
The ability to use the CatDV Serer as a license server is designed to make deployment on a network easier so you don't need to configure each client separately. There's some flexibiity built in and licenses are freed automatically (after 12 hours I think), so as the network configuration use of machines evolves over time you can use the license on the new machines without having to manually clear it from the old ones (or use a dongle or enter MAC addresses or anything fiddly like that), but the basic license terms are unaltered.
