An interesting open source development in the U.K. announced last week; from the press release:

The Universities of Oxford, Cambridge, Hull, and the UHI Millennium Institute announce the formation of the Tetra Collaboration, the outcome of a series of meetings and a major summit held at the University of Oxford on the 25th-26th September 2006.

The goal of the Tetra Collaboration is to coordinate activities across the member organisations so as to more efficiently develop and deploy open source enterprise applications of use to UK and European universities and colleges. By working together we can share common solutions to better serve the needs of students and academics, and each of the institutions named is committed to making tangible contributions into the collaboration.
