So, if you’re a small independent software provider in need of an inexpensive way to license MSDN, several internal use licenses for Vista, XP, Office; in addition to, SQL Server® 2005, Exchange Server, SharePoint® or Windows Server; you may want to check out this program.
The Microsoft Empower for ISV Program is an initiative for independent software vendors creating new software solutions using Microsoft® technology. Membership gives you access to essential development tools, resources, and support. This is all available for U.S. $375 per year.
This is really not bad when you consider the annual subscription for MSDN alone. For more information and to see if you qualify go to Microsoft Empower for ISV Program (http://www.empowerforisv.com/)
