Scientific publishing is important. Hadoop was possible largely because Google published SOSP papers on map-reduce and google file system. Many of the current NoSQL stores are based on ideas from the SOSP paper on Dynamo key-value store from Amazon. However, it is important to realize that Dynamo, Google File System, Map Reduce were all working systems first and publications later.
Unfortunately, there is no incentive built into the academic research process today for building working systems. It is not necessary for promotion/tenure/awards. The incentive structure for systems research is what really needs to change.
Many universities realize that there may be valuable technologies that need to be extracted and developed. Business schools try to match MBA students with Engineering students, offices of tech transfer try to offer some support in this area as well. Schools are offering specific advanced programs in commercialization of academic research (e.g. Notre Dame's ESTEEM program http://esteem.nd.edu/). Even some companies are trying to help this process, like TandemLaunch (http://www.tandemlaunchtech.com/).
