The Developer Tools license model
Previously with BizTalk Server 2010 you have bought BizTalk Server Licenses for servers only (Branch, Standard and Enterprise). The Developer Edition was free. With 2013 you must purchase this license per user, if they do NOT have MSDN. This is a per user license.
“You must acquire a license for each user you permit to access or use the software. You may install any number of copies on any number of devices for access and use by one user to design, develop, test and demonstrate programs. Only licensed users may access the software.”
My interpretation of “access the software” (but I am not a license expert!) is that it is ok for BizTalk Server to exist in a test environment where it routes traffic and perform integrations to and from other systems that at their end have users, devs or admins that are not licensed. It is also ok for other users of the same server to access the server where BizTalk is installed to, for example, administer Windows (as long as that in itself is properly licensed). The limiting factor are the users that in some form access the BizTalk Server software itself. Such as deploy, configure, administer or in other ways interact with the BizTalk Server GUIs or services.
Target prices seems to be around $37 Estimated Retail Price (ERP). https://mspartner.microsoft.com/en/us/Pages/Licensing/Downloads/open-license-estimated-retail-price-list.aspx
I have also seen $36 for price level C. https://mspartner.microsoft.com/en/us/Pages/Licensing/Downloads/open-license-level-c-estimated-retail-price-list.aspx
To those with an MSDN subscription (http://msdn.microsoft.com/subscriptions) the list of subscription types that has access to this seems to be quite large:
VS Pro with MSDN (VL)
VS Pro with MSDN Premium (Empower)
VS Pro with MSDN Premium (MPN)
VS Test Pro with MSDN (Retail)
VS Test Pro with MSDN (VL)
VS Ultimate with MSDN (MPN)
VS Ultimate with MSDN (NFR FTE)
VS Ultimate with MSDN (Retail)
VS Ultimate with MSDN (VL)
VS Premium with MSDN (MPN)
VS Premium with MSDN (Retail)
VS Premium with MSDN (VL)
VS Pro with MSDN (Retail)
How do I get it?
Summarizing from above you would either have an eligible MSDN subscription, or you get it through traditional volume licensing channels.
