I think I asked about this in the comments of some Microsoft blogger, before. I wish there were an easy way to find my comments and add the good news.
Visual Studio 2005 / .NET Framework 2.0 Go-Live License
Microsoft’s Beta EULA does not permit production deployments of customer applications. In response to strong customer demand, Microsoft will provide an addendum to the EULA for some of the pre-release products listed below. If you are interested in deploying an application built with Visual Studio 2005 Beta 2 or Visual Studio 2005 Release Candidate in a live production environment, please see the Visual Studio 2005 / .NET Framework 2.0 Go-Live License.
Visual Studio 2005 Team Foundation Server Beta 3 Go-Live License
Visual Studio 2005 Team Foundation Server Beta 3 can now be used in a production environment. Microsoft is committed to supporting a complete migration from Beta 3 to the final RTM version of Team Foundation Server. Details of the Visual Studio 2005 Team Foundation Server Beta 3 Go-Live license will be forthcoming.
UPDATE: I found the comments I placed in Soma's blog. He responded himself to the question about the Go-Live License here. Thanks!
