While this isn't really programming related, I'll answer anyway.
The developer edition is not, in fact, available to everyone. To the best of my knowledge, the only way to obtain it is via an MSDN subscription (not TechNet, I don't think; sorry!) that includes server software (so something above the "Operating Systems" subscription level).
I'll give you the benefit of the doubt and assume that your need for the enterprise only features is for a development environment and that the deployment environment has a valid license for the enterprise edition. If that's the case, then you'll have to obtain an MSDN subscription.
Out of curiousity, what "enterprise only" features are you planning on using? In my experience, a fairly small percentage of developers actually need anything above the functionality offered in the Standard edition.
