@Dr Herbie:According to the blog post that I linked, TFS2010 doesn't come with any CALs. However, you can have up to 5 users connecting to a TFS2010 deployment without a CAL, if that makes any sense at all. If you want 10 users on a single deployment, you need TFS2010 + 5 CALs. Should you ever decide on a 2nd deployment of TFS, then 5 of those users with CALs can attach to both deployments simultaneously, while 5 have to remain on only one. However, the 2nd deployment can have an additional 5 users without CALs as well. Clear as mud.
