After more than four years, things are quite clear:
"Except as provided below, you may not use the DreamSpark Direct Subscription software for commercial purposes or commercial software application development, publication or distribution unless you first purchase the appropriate commercial license(s) for the software."
The above text is exerted from:
Microsoft Software License Terms
MICROSOFT DREAMSPARK DIRECT SUBSCRIPTION AGREEMENT
